I [23M] got back with my ex [21F]. Should I have moved forward?

All of this is pretty fresh, so I really don’t know how to feel about all of it at the moment. So basically I started dating my gf last October, and since it was my first real serious relationship, I struggled a lot at communicating and showing my love earlier in the relationship. By the end of November, and into December, all we did was fight, and she ended up slight cheating on me by talking to guys about meeting up (who weren’t from our country, so take it as u will) and on sum weird shi, and all together anything that I wanted to know that she did, big or small, she would hide from me until I kept asking and eventually she would open up. This led to major trust issues on my end, and us almost breaking up in December, and although she hasn’t done anything since and has gone the full extra mile to make sure I feel comfortable in the relationship, a few days ago I decided to end things because I felt like I was becoming too controlling of her and couldn’t trust her as my partner.

I really do still love her, and I know she still loves me, but I don’t know if getting back with her was the right decision since so much has already been done in terms of me breaking things off. Idk what to do. Should I have done this, or just let it go and move forward?
