Evening gents.

TLDR; 2 year ex-LTR wanting to come back to me after I cheated. Only problems are she's had sex with one guy since we split and has told her parents and girlfriends I cheated. Still worth a shot or is it an obvious next?

LONG version: LTR was a good investment. Loyal, only had a notch count of 1 other dude (confirmed after thorough investigation), cooked, cleaned, smart and brought a hot body and good sex into my life. I applied a constant low level of dread by lifting and maintaining my social life/aloofness whilst hers diminished to an extent. This may sound romanticised but it reached the point where she'd drop anything for me at any time, bought me expensive gifts (not essential but appreciated), and was openly comparing me to other men as a king and other fluffy stuff like that. Can say I genuinely enjoyed my time with her.

Now 6 months ago (18 months into LTR) I kissed a girl from a similar social circle at a festival whilst drinking. No excuse I know. I beat myself up internally for a long time, concealing it from my LTR. Decided telling her to relieve my guilt would be selfish and was not worth breaking-up over. Internalised my guilt and used it to agree with myself not to slip up again.

Since then, rumours escaped and reached her. She pressured me about it roughly 4-5 times. I flat out denied it, assuming it would blow over. One dude from her work (casual lifeguarding) in particular had been feeding her stories about me any chance he could; I told her he just wants to fuck her and to not pay attention to him.

Fast forward to roughly 20 days ago. She called saying someone showed her evidence of me being unfaithful and just wanted me to come clean so we could try to work through things. I said "yes its true I kissed her" not realising she'd baited me into saying it. The fallout and breakup was what you'd expect, a bit messy. Honestly I was crushed for losing something good due to my own actions but decided frame was the one long-shot I had at recovering things so I applied radio silence after saying I appreciated her anger and wished her a happy future if she wanted to move on. Accuse me of oneitis for this but I didn't want her to move on.

Only a couple days later she was back messaging me albeit not too pleasantly. I got her back onto talking terms after a few days and a few sparse cleverly worded texts. I saw her in person and she cried to me, sobbing about missing me and said she didn't mind the kiss it was just the extended lying that had killed her trust. I tried to pull a risky move with a high chance of losing frame entirely; tried to suggest I was still keen on recovering things between us. To do that, I was willing to provide her with my phone whenever she asked for it and to reply to any messages asking where I was ASAP so as to regain trust. She didn't seem enamored so I assumed it failed and left.

I need to mention this was VERY VERY hard to pull off whilst maintaining any sort of frame and I realise by this point I was taking a last-ditch effort. I do not recommend doing this. IF it is done, emphasis must be put on YOUR desire to fix things because YOU value the relationship, not begging or seeking her forgiveness or offering yourself up like some injured lamb because even if she does come back to you, you'll be grovelling and she'll be in the drivers seat and it won't end well for you.

Anyway, it worked. However not smoothly. Another week later (4 days ago or so) I saw her and she was much better however she said she had decided we should move on after considering my proposal. I agreed and assumed my proposal had not worked, however took the opportunity to give her a last good pounding and I will admit she was wetter and gagging for it more than ever before.

Unbelievably she came back two days later (two days ago from now) and I decided it must be for another good cocking. When I went to give her the time however, she became withdrawn and I pressed the issue and she came clean. She had fucked the dude from her work that had been badgering her about me a few hours after I had fucked her two days before. She went out and got drunk and he was there (fancy that).

Funnily enough, now she's the one apologising and wanting to come back to me. Her hamstering for fucking him, copy pasted directly from a message she sent: "the main reason is because I knew he'd be receptive and I knew he liked me and would probably want to see me and stuff, and because I love being your girlfriend so much I just wanted to be a girlfriend again so I wouldn't really feel alone". She's offering large investment back into recovering our relationship and seems. willing to make compromises. I have been distant whilst I mull it over, thought I'd throw it up on asktrp while I sleep on it. I know this will divide most guys on here and most will be all for dumping her ass. Just like to see some thoughts accompanied with reasoning to help set my head straight.

Oh plus she's told her folks that I cheated on her. Sounding more and more of a toxic wasteland by the minute now that I'm typing it all out.

I know this is somewhat of a red herring and I am not asking for moral advice or a lecture on cheating. What I seek is advice from others that may have been in a similar situation/anyone that may be able to read my story from an outsider's perspective and add their 2 cents to help clear my perspective. Please try not to provide disdainful opinions, I'm not as brushed up on RP theory as some and would appreciate leveled suggestions to help me at this point in my life.
