Female Friends

So this was like a whole debate at work 😂 but if your s/o has a female friend but you have this weird feeling from her side it’s not that u don’t trust him , u don’t trust her , and your partner just makes it seem like you trippin and doesn’t want to cut them off , how would y’all feel what would u do about it ? , personally I’m cool with my man having female friends at work or whatever but i don’t see a reason to have their number or something always talking to them am i wrong ? Best answer i heard was it all comes down to respecting your partner , for me the problem was i let it happen and the shorty start getting too comfortable but ofc he failed to realize that and always defended her every time i brought it up , one time he told me people would think that him and her was a couple so it’s like am i really wrong for telling him to cut her off ??? One time had this weird feeling went on his phone and caught him texting her at 5 in the morning asking what time she started work (all work at the airport) she told him the time and everything he says alright bet . Confronted him about it told him it’s her or me to delete her number ... next thing u know all he did was erase her name thinking I’m stupid 😂 then it finally stopped , So it’s like how can i trust having female friends ? It’s not even a controlling situation in my eyes 🤷🏽‍♀️been with him for almost 4 years this happened last year and I’m currently 19 weeks pregnant but all of a sudden he feels controlled and brought up having friends of the opposite sex 🤨
