ADVICE: My Boyfriend is Obsessed with My Boss

Hi,
I don’t know if this is the right email that I’m suppose to send this article to, but I need help from readers please.

So I’ve been dating this guy for a year now and i think he might be obsessed with my boss at the office. My boss is a very pretty mulatto, tall and married with 2 kids.

Ever since I showed my him her picture, it’s been something else. It started with him always asking about her everyday. At first I didn’t see it as an issue, but then when it generated to him telling me send his regards to her and that he loves her (which he said jokingly) then I started becoming worried. I confronted him about it and he said I was only being jealous and he was only joking.

2 days passed and he didn’t mention her again only for him to ask me if she was married, which I told her right from the beginning and also asked if she has a son. Just last month I was working with her when he called and I told him I couldn’t talk and that I was with her and we were working in something, you needed to have seen the shock on my face when he asked me to send him her picture. Is my boyfriend obsessed with my boss who is married with 2 kids? Should I be worried or am simply overreacting?
