Hey guys, need some red pill advice in this situation. Both 26 years old.

I have been living with my now ex gf for 6 months (I know do not cohabitate). Originally, I was moving in by myself but she helped me move my stuff to the new place and with lockdown, she basically started living at mine and sub letted her room to her friend.

We have been dating for a year and half and made it official a year ago. However I’ve noticed in the back of my mind I’m losing attraction to her as she has put on weight. I also noticed that I do want to fuck other girls. Also, when living with her Im not able to focus on myself and my development which was also a problem but not her fault.

Recently we have been having petty arguments where she gets offended by anything, and then I have to apologise which is annoying and makes me feel like I’m on egg shells. There was also an issue with last name, she said she would take my name but keep hers aswell and that would be the same for the kids. With a scarcity mindset I gave in accepted it as she is really good to me cooks for me, gives me compliments etc.

The biggest issue is she gave me her old phone for work. I obviously had a look around but there wasn’t much to be worried about. However when i installed WhatsApp some old chats with friends from college came up.

One message read: went out last night, still be my slutty self but trying to behave and not go home with anyone lol

Message to another friend: one night stand isnt that bad, I’ve had too much to count it as bad now lol

Now I know she had abit of fun in college with drugs and guys (she mentioned it) but wasn’t prepared for what I read. When we’ve discussed it before she always said I was focused on work, didn’t have time to date, would prefer sex with someone im comfortable with yada yada (our sex is good btw). But was still shocked to see her refer to herself as slutty and proud as well as a player (I think she has self esteem issues from daddy issues and first bf at 21 cheated on her etc)

She’s coming tomorrow to pick up some stuff and wants abit of closure on us as she is confused on why we broke up so do I tell her the real reasons or just play it off as I need be alone and work on myself etc. FYI I’m definitely leaving her, I couldn’t look at her the same after seeing those messages. I do however care about her and don’t want to make feel more shit.

Thanks in advance.
