<human>: The man I've been with romantically for two years and close friend got his neighbor girl pregnant. I just moved to their block two months ago, right before I found out they were sleeping together. Was mad, we fought, etc. etc. Found out last week she is pregnant. He still wants to be friends with me and have sex (which is awesome, btw) and I have to see them all the time, together and apart, while walking the dog going to work, etc. I need some advice.

So stop having sex with him... then what? Still have to see them all the time, and he will still call and text me all of the time.

We've been best friends for the last two years and though we were usually sleeping together, we were never exclusive, for many reasons, including a large age gap. I moved to the same block as him (my first mistake), right after I moved I found out they were sleeping together, I was hurt because he lied about it. But still friends. And now this happened. I don't want to loose my best friend but I definitely don't want to loose my best friend and have to see him and his baby mama ALL of the time.

I am 22/f, he is 39, male.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Fuck buddy/Best Friend/Neighbor got his other neighbor pregnant. Don't want to loose friendship or see him if I do.
