<human>: Can you give me a shortened version of the text?

Together 5 years, moved cross-country together for our studies/careers recently and it's working super well. He's just started going to an acting class where the other people are really talented and he obviously wants to get up on that level. Of course I'm extremely supportive and proud of him and really happy he's finally able to exercise his passion for acting properly (our hometown didn't have the accessibility the big city does.) 

Last night he came home from class and sat me down to talk about how I feel about him kissing other women onstage. Until I was faced with it head-on I thought I'd be cool with it, it's just part of the job right? But just imagining him being with another woman, meaningless or not, tears me to pieces. I'm very monogamous and he's always said he is too, and that this is just what he has to do to get ahead in the biz. 

I get that, and the rational part of me knows he wouldn't be feeling anything except wanting to get it over with. But I can't even bear to imagine it without feeling upset, because he's a REALLY good actor and he'd be pretty convincing. He's really into method acting so my understanding is that he would go into character deeply in love with his co-star. Him having loving thoughts about another girl, even if he's in character makes me jealous and hurts me.

Maybe I would be ok if it was a one time thing, but he's serious and committed to acting and it will probably happen plenty of times. I don't want to be uncomfortable with it, but I don't see how I can change all my views and be ok with it. Help!
<bot>: Boyfriend is a talented actor who will inevitably have to kiss other women at some point in his career. How do I move past my jealousy and insecurity?
