I've been dating a girl for almost a year. For the first 8 months of it I was in beta mode although the sex never slowed to less than once a week, she obviously wasn't that into it. Thankfully I found TRP a few months ago and started taking action. I've made a lot of changes and she has definitely taken notice. We're having sex as often as I want now, she initiates it often, and she's even doing things with me I know for a fact she's never done with anyone else. (Anal, public sex, etc.) So things are pretty great in that aspect.

The problem is that she recently confessed to me that she got drunk and cheated on me about a month into our relationship. It was just a one time thing and nothing more than a drunk fuck. (I even contacted the guy to confirm and he was cool and honest about it) She also told me about a few guys she used to Snapchat and text. (Contacted as well) She told me that was the only time she has ever physically cheated on me, and that the orbiter stuff stopped many months ago. I know woman like to tell half truths, but she didn't have to tell me everything she did, and from her body language (I've gotten good at reading since I started paying attention) I'm inclined to believe her.

After thinking things through and talking with her, I told her that i was willing to try and continue the relationship, but that she would have to earn my trust and that there would be consequences for her deception. I also made it very clear that if she wasn't completely honest and loyal from this point on, then I would walk immediately and replace her. She's at a point where she knows she needs me and actually appreciates my SMV, and I think that bit of dread really got to her.

She's completely deleted Snapchat, removing any old flames from social media, and is even making her accounts private so that she doesn't see messages from them. She has given me complete access to her phone and is cool with letting me look through it anytime I want.

I know I probably should have ended things as soon as I found out about TRP, but I used her as an experiment, and although I'm sure she remembers some of the beta behavior, I think I'm quickly replacing those memories. I don't think I'm having oneitis for her because if she fucks up again I know I would be fine walking away and could honestly do better. I really do like spending time with her though and the sex is pretty great. I know LTR is hard mode, but I like the consistency and bond that grows with time, and would like to try and make it work. What are your thoughts on the situation? Am I being naive and making a huge mistake?
