Hi,
My relationship will be 4years this month… I love my partner and he loves me too but he doesn’t know how to care whenever am sick, he expects me to up and ready to start working two days after being sick, if not he starts getting grumpy in the house cos he’s doing most of the chores I do on a normal day.
He also has a habit of wanting to meet different new girls, calling and chatting with them late at night, and whenever I raise my concern about it he gets upset and tells me that’s his own way of meeting people, that he doesn’t know who might help him later in the future. I feel disrespected by that tho( my partners idea of cheating is only sex)
He also doesn’t like me showing my emotions, like he wants me to bottle up my emotions and not express them. He gets upset when I express my emotions, in his words he said I complain too much, be it sickness, sadness or any form of complain. I’m tired and at the point of losing it. Or could I be the problem?
