Cheating boyfriend problems

Basically my boyfriend cheated on me with a girl he works with about a month ago. I’ve chosen to try and forgive him and move forward from this all.

We’ve been really good together since which sounds silly but we have. I don’t want comments telling me to leave him he’s the love of my life and he’s been since I was 14 we have a 6 month old together, we’ve spoke about everything and he’s very apologetic, massive mistake and all that. It’s my decision to try and move forward with him.

Anyway the girl he cheated on me with just keeps posting things about how she’s sad he’s with me, and he doesn’t love me, and she can ruin my life with screenshots about what he’s said or what they’ve done or whatever. They still work together he is currently looking for a new job and has interviews this week.

Anyway I just can’t help looking st her social media pages, I know I shouldn’t but she’s constantly putting stuff up about me and him. I don’t know if she’s doing it because she does have things to tell me and she’s just not saying anything or she’s really likes him and she’s genuinely upset he’s stayed with me.
