My father in law completely ruined my relationship

My father in law doesn't like me. Nothing new. He told me from the beginning that he doesn't and I've made myself clear on my intention for his son. (Even tho he has no say in anything) we ignored him and its 7 years we've been together.

My father in law remarried and now he have a partner to help him target me. I've stayed away and had nothing more to do with him and his life.

Now I'm getting msgs from my boyfriend stating that he needs space also and that he's tired.

???

What am I to do? Just end all this messy drama and move on?

I'm with this guy for 7 years and all 7 years it was happiness (minus his father)

Am I to walk away or continue fighting?

:(

Signed

A tired woman
