So me and my boyfriend were together for 4 years when he decided he didn't love me anymore and left. He hooked up with multiple girls, ignored me, parted, and didn't bother with our baby. I know he took a 360 and turned into a different person. Everyone was questioning me and I even questioned myself sometimes why I tried so hard to get him back. I found out he left because there was problems he didn't open up to me about between us. I mostly wanted him back, because coming from a broken family growing up I wanted ours to really work and because he was also my best friend for all those years when I had nobody. Long story short we ended up working it out and problems have been solved and we are doing much better. Him gone and me going through the pain of him being a huge jerk and let down lasted about 2 months. Even though we are better now maybe even better then before I can't help but cringe and wanna cry remembering what I went threw with him. He packed his stuff and left when I was sleeping so now I'm terrified of going to bed before him or even napping if he's not. I'm scared he'll go run off with another girl if I mess up even a little bit. He has no contact with any of the girls he hooked up with or doesn't even talk to anyone at all other then family. He swears he loves me and I believe him, but I can't shake off this depression of the events that went on. He doesn't know I feel this way and I know he wouldn't know what to do about it other then be here for me and reassure me. I need advice on how to move on from that past. It's only been about 2 months since it's happened so it's still reasonably fresh to me.
