Don't like that he's flirting with other men?

right? like I’ll let it slide this time since angel was drunk a little

We're all different and we build relationships differently.
Angel is very flirty and as he's said to Allen, he's never changed his essence for Josh. He made adjustments cuz he cares for him and loves him, but he's not changing to be another person.

Also love and attraction don't align necessarily.
Angel is very confident in his sexuality, and expresses very easily his attraction for other people, but he loves Josh. And Josh might get jealous sometimes (which is okay) but he's not hurt, cuz he knows he is loved and that Angel wouldn't cross the boundaries they imposed on their relationship

I don't think respecting the relationship your in by not blatantly flirting with other men that man being your current boyfriends ex that left him for another man that he married in front of your partner at a going away party for your former boss is changing yourself it's just being respectful...

Plus I know everyones relationships are different that's why I said I don't understand it. It's not like I only see my partner just cause I love them doesn't mean they are the only person I'm attracted to, but because I love them the idea of doing anything that would wipe a smile from their face in any way shape or form doesn't sit right with me at all so I don't understand? My partner trusts me too and knows I would never cause they know how strongly I feel about stuff like this, but just cause they trust me doesn't mean I'm gonna play with their feelings by testing the waters to get a reaction.
