Break up and make up

This is a long one.. sorry.

So I’ve been with my partner 6 years

He has been controlling, physically and mentally abusive, cheated on me the whole time and basically had a double life.

It took me a long time nearly 5 years to gain complete courage to leave and cut him off..

we have. 3 year old together.

After we broke up around a month after I started going on some dates with another man,

(Meanwhile he is doing the same thing)

My best friend and I had a holiday booked and this man was coincidentally going away and staying around an hour away from where I was for work, for a month.

And my trip fell within these dates.

I obviously didn’t tell my ex that I had been on any dates with someone or that he would be abroad.

I had planned to meet up with him with my friend for drinks and dinner ect, one thing let to another and i slept with him,

We got into a bit of a holiday romance situation, and got a bit carried away!

we had lots of pictures taken which he put on Instagram! And these made there way back to my ex.

He absolutely lost he’s lid, and stopped seeing my daughter for 2 months to punish me I guess he thinks he was doing. Mean while he was dating the WHOLE time.

in October we finally spoke again and he was sorry for what he had done in the past, and he wanted to get back with me. And that he had changed.

He promised that he wouldn’t Chuck this back in my face and that we would move forward.

I wasn’t sure about it, but one thing lead to another and I fell pregnant, now 16 weeks..

he keeps bringing this up constantly, throwing it in my face,

Telling me hes just pretending To be happy.

He wants to know every little tiny detail of what happened . When I don’t even know anyone he slept with while we was broken up, as I don’t even want to know.

Am I wrong??
