<human>: Could you distill the essence of the text into 1-3 sentences?

To give some background, I was a very heavy drinker (I cut down a lot after our breakup, as I didn't want to start relying on it to heal the pain) and my ex has severe attachment issues and problems with commitment which led to us having some issues after 8 months. Long story short, she cheated on me and I lucked out and semi-caught her.

The next day, we broke up. She admitted to the cheating the day after but admitted she would never have told me if I hadn't happened to catch her. The next few days involved several texts of her talking about her attachment issues etc and how she's cheated on the other 2 people she loved "because it makes the breakup easier"

We stopped talking for a few weeks but then went back to being friends that instantly turned into FWB. It's been a couple months and things have been really good and she's started to try to get back together. We've both made some changes (less drinking, countless talks about how we treat each other and what we want etc.)

I can't possibly forgive her for cheating on me and in a way I'm really mad because it seems like she never really had to pay for her decision. I never stopped loving her and I do believe that she loves me but I don't really know if I can ever trust her again.

I guess I'm just asking if anyone here has had any success/failure forgiving infidelity. I absolutely love this woman and we get along great but I can't tell if she just got scared of the commitment and made a mistake or if she's playing me and this or something equally bad would happen again.

Thanks, Reddit!
<bot>: GF cheated on me, we've been FWB for a few months since. She's started to talk about wanting me back and I'm looking for advice.
