DP has been one of these ultra competitive people who's always no. 1 at most things. When he met me, he said he felt intimidated by my intelligence etc. and never had that with a gf before. (I think part of it is his bravado of confidence and competitiveness hides a bit of an insecurity) and he's one of these CEO types.
I find that whenever we play board games with another couple etc he always seems out to "get me" if that makes sense - like those games where you could take cards or points from another player, it'll always be from me and he'll try and say I'm cheating at the game because X, Y, Z (often naive mistakes I've made as I'm new to the rules). Whereas the couple, he has known them over a decade (DP has only known me 2 years) so it's not like he's not familiar enough with them to do this stuff to them.. if anything he's known them longer.
How is your DP during board game nights with other couples? I wouldn't mind if he did that with everyone but seems targeted only at me.
Also, he always actively encourages me to be part of the convo and asks what's up if I go quiet but if I say something funny etc. in the group of his friends, his friends will laugh but he'll often seem like he's not even listening..
I don't know if I'm just being oversensitive, overanalytical and this is just typical partner behaviour or it's just showing what's underneath the surface.
