Where Do I Go From Here?

I broke up with my girlfriend (of a year and a half) 10 days ago and instantly regretted it. I’m in therapy and recently sober. The last straw was seeing her alone for less than one day a month. She’d want me over more often but she’s different when her kids are there, which isn’t a problem, she’s just in “mom mode”. As a new couple who doesn’t live together, I wanted time to see who we were outside of being parents and to continue to get closer romantically. Was I being I reasonable? Now we are talking again but have both decided we can’t go back to the way things were. I’d build up resentment and then drink and lash out. I know I need to work on my own insecurities and sobriety. I miss her and I get the feeling she’s just waiting for me to move on because she seems more okay with the break up. I hate this limbo and just want to focus on my own health and healing but this thing between us is so confusing and frustrating. Do I just move on and pretend I’m not in love with her? Just accept that we aren’t good together and she can’t give me what I want? Or do I deal with the discomfort of being in limbo while working on my own issues and she works on hers until we can be in a better place together? Should it be this complicated?!
