<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've been in a long distance relationship with a boy and we recently decided I should move to him. It's a big move, cross-country. I'm fine / very happy with it.

When we first met, he tested positive for a STD -- and subsequently I had to get tested for that. After he got treated and I didn't end up having it -- we agreed to have a monogamous relationship going forward.

Anyway, apparently it was his ex that gave this to him. He is very close with this person and regularly visits him. He's made it clear to me he will not pursue anything sexual with this person going forward.

It makes me feel weird that he continues to spend regular time with this person at his house (sometimes alone together). I am not jealous but more concerned that by putting himself in temptations way it could set things up in a bad way.

Am I being out of line? I haven't said anything to him about it yet.
<bot>: I'm nervous about my boyfriend spending time with his EX that gave him a STD. Especially because of the big commitment I just made to him and the newness of our relationship.
