Advice please 🙌🏼

So I’m no longer with my baby dad we broke up weeks ago. I met this guy and everything was going so well we really liked each other until then he started acting really weird because my baby dad comes up to visited his child all he kept saying he doesn’t want my ex near me.

Saying that I was defended my ex to him when I wasn’t. I don’t know why I apologise for absolutely nothing. Then wanted my ex to messaged him.

While he was working he was really dry with me ever since my ex came to visited his child. Making me super stressed and overthinking.

Then he apologised and says it was his insecurities that he didn’t wanna lose me saying he loves me then said “I need to sort my head out” all I’ve done is trying to fight for our relationship but he just kept saying its his insecurities

And he knew I was going out shopping with my brother and his reply was take it you’re meeting her dad thought we had plans but sure….

My friends saying he’s a massive red flags trying to twist things on me.

So I ended it with him and blocked him on Facebook this morning and then he added me on Snapchat about 6 in the evening just to blocked me. I think he’s raging that I blocked him.
