My partner recently got in touch with an ex girlfriend. They are fb friends and he wanted to reminisce about a funny time they had once together. Anyway, I'm not 100% ok with this but partner has been transparent and it was nice he was trying to include me.
Ex girlfriend is now messaging more often and now signs off with kisses. The odd code word from their relationship or phrases that aren't funny to me (because I wasnt there!) are starting to creep in and I don't like it!
I know it makes me sound jealous but I worried they will develop feelings for each other again.
They split up 20 ish years ago when she went off to uni.
Would ibu to ask him to give the messaging a break for a while? Just until we can establish some boundaries? I dunno if I sound nuts here!
