Advice please?

Molly

So my partner and I were together from March 2018 until January 2019, after that we kept sleeping together and I ended up pregnant January 2020. Last month we decided to get back together. In our first time together I was 17/18 and it was my first relationship so I freaked out about him having any female friends etc. I’ve grown and learned and this time I don’t care apart from this one girl.

- they were sleeping together before I met him but I didn’t find out until wayyy after we broke up (we all hung out together during the relationship so a mention of it would have been nice)

- they slept together after we broke up also

- whilst we were together he commented on one of her photos saying ‘boobs 👀’ because they were practically hanging out which my boobs being small is my biggest insecurity so that pissed me off

- on nights out during the broken up period she would stand outside the pub calling me and my sister ‘sluts’ and ‘bitches’ for no reason, she also tried to start arguments with me on multiple occasions and would mutter stuff as I said no and walked off (nothing gets solved when you’re drunk)

- she constantly likes and comments on everything he posts or is tagged in apart from anything to do with me

I want to talk to him about how uncomfortable it makes me that they’re friends but I’m worried that he’ll freak out and call me a psycho etc. because of how I freaked out about every girl during our first time together.

I just need some advice on whether I’m overreacting because it makes me physically sick thinking about them being around each other and I want it sorted before baby is born in 11 days 😣
