Was with my ex from 21 I'm now 29 (he is 32) we have 4 kids. When I got pregnant with the youngest he had some mental health issues which resulted in him being sectioned, the mh issues revolved mainly around me and thinking I had done things I hadn't. During my pregnancy he broke up with me because of it and completely disappeared. To the point I heard from him maybe 3/4 times during my whole pregnancy, when he would just randomly block me and stop talking to me for no reason. Anyway he wasn't at the birth but he got help and contacted me when my baby was about 6 months old. Obviously due to everything that happened I was very wary about letting him back into our lives but he assured me he had got help, was much better, wanted to step up ect. And the children wanted to see him again. Well he saw them 3 times, in 3 months. So basically he would see them once then go a month without seeing them and couldn't see why this was a problem. Anyway he has now decided to go no contact (hasn't seen them since 2nd of January) and no contact at all. I can't help but feel angry that I let him back in after everything he did and then he just walks away as if we don't exist. I can't stop feeling bitter and it's really bothering me that I gave him another chance. How do I stop feeling like this as it's really eating me up! I doubt we will hear from him again tbh.
