Baby daddy or Husband?

I’ve been having a lot of things running through my head my and my husband of two years have been having a hard time since about two months ago when he got home drunk and said it would be better if we just get a divorce because I deserve better. And all this jiberish I was like look fool if I wasn’t happy or if I thought I deserved better I would of been gone a long time ago. Me and my husband have been together since 2013 on and off then finally got married in 2017. When I was 16 I got pregnant with my sons father we were dating for a year and we had a kid 5 months into the pregnancy we end things I’m broken depressed see my sons father ended up moving to Florida 3 months into our relationship in the summer of 2009 he flew back to visit for the summer when summer was almost over I convinced my parents to let me visit him a week so there goes my hot ass to Florida well coming back home I realized I missed my period even my mother was questionable because our periods came around the same well I was lonely the whole pregnancy after our kid was born we were on and off after his cheating back to back and finally realizing I needed some who loved me for me I left..... so fast forward for today I’m married my sons father has been in a relationship for about 8-6 years with another girl and our coparenting has went from toxic to understanding to very good venting friend (I know it’s bad but I have no girlfriends to speak to) so yes me and my sons father flirt well he flirts and I’ll politely shot him down with we’re married and happy don’t go there.. I always keep my evidence just in case... so yes me and my husband it’s like we haven’t had sex in 2 months he’s always on his phone always in another room never wants to cuddle at night I’ll try to turn him and and he’s just like not today.... I don’t know if I’m not attractive enough for him anymore or he’s cheating or whatever I’m not sure. So then for the past week all I have been dreaming about is my sons father not specifically cheating or anything but just dreams as if it’s back in the days and we’re hanging out in my room just talking I’ll wake up laughing and just thinking about him.. of course I will always care about him he’s a good person at the end of the day and that’s my sons father. But why know? Why pop up now? I’ve just realized I miss his attention, my husband isn’t the affectionate type either. So maybe I just miss being loved by someone.
