First of all, I want to thank all of you for your opinions and advice, I read all of it and decided to proceed with caution as I got scared for my son's safety. So yeah, here's a small update.

On Tuesday, I contacted my ex-boyfriend about his mother's and sister's behaviour. He was absolutely taken aback as he hadn't known any of this and had no idea I was even back in the country. Both of us were a bit unsure of what to do next but decided to meet up the following day to talk about it and (as many of you advised) to let him meet our son. He asked for a picture of him and when I sent him one, I could hear him burst into tears on our call and it really hurt me to know how much this impacted him. He then told me how he was pressured into not talking to me as his mum threatened to disown him if he did. He was scared to lose his family's support and that he'd be unable to fund college otherwise. I understood his perspective and told him that we were both young and naive and didn't really know any better.

He vowed that he'd care for both me and my son but it's honestly too early to figure out whether that's true or not. But we seem to get along just as well as we did when we were still a couple. He promised to talk to his mother and sister and also mentioned that I should consider filing a report which I'm still unsure about but am considering doing.

He met my son yesterday and it went about as well as it could go. Seeing him made me all emotional aswell and the moment we saw each other, we both started crying. It was a wonderful day that we all got to spend together and it honestly made me think of what life could be if we could be a proper family. My son absolutely admires him and after we went home he asked me, if "dad can come live with us". I honestly started crying again and called my ex the same evening, asking him to meet up again soon.

We'll see where this is heading but for now, his mother and sister have left me and my son alone, no calls, nothing.

Any idea if I should still press charges and how I should go forward with my son and his dad so I overwhelm neither of them?
