I've not posted here much but I'm wondering what to do.
I did make a thread when I was pregnant but I'll give background: me and my ex got together in March 2019, last year just before lockdown I found out I was pregnant. We were both 15 so we were shocked but he said he'd support me if I wanted to keep the baby or have an abortion (he wanted to keep him). I told my mum straight away and she was supportive but his parents weren't and they were quite angry. Lockdown happened so we didn't really see eachother we just texted and FaceTimed but in July we started arguing over silly things and our relationship got toxic. I also found out he was messaging another girl and he was also taking drugs with his new friends so I broke up with him and he got with the other girl. He didn't message me until the end of November asking how I was and apologising and he said he was embarrassed as he was 15 and all his old 'mates' left him because he was going to be a dad.
I gave birth in December and I messaged him and he met our son when he was 5 days old and we spent that day together and he even held son for abit. He was going to see him a few days before Christmas but then he said he couldn't so we saw eachother the Monday after and he gave me some money. We then saw eachother nearly every weekend and he gave me money (not officially though just when he saw me) and he was amazing with son with feeding him etc and he even bathed him a few times.
At the end of January it was his birthday and his mum wanted my ex to have son alone that day, I said no as son was only 7 weeks. His mum then accused me of stopping him from seeing his son (I wasn't and my ex didn't mind anyway as it was his mums idea). His mum then told him to 'leave me to it' and told him to he a teenager and spend time with his mates. He obviously didn't and carried on seeing me without his mum knowing. His mum then found out and was annoyed and took his phone so he couldn't message me. One of my friends said he was probably lying but i don't think he was as if I didn't want to be involved with son I don't think he would've replied when I told him I had given birth (when he replied he asked how me and son were and then we texted abit and then he asked if he could see us that Friday).
After that he still saw us despite his mum. On Saturday he apologised for how he treated me (he already did previously) I told him I forgave him as I have to focus on son and he is an amazing dad to him. Then he asked me if we can get back together as he's grown up and wants to be there for me and son and he told me he wishes he never cheated or got into drugs.
I'm not sure though. Any advice will be appreciated
