How will you feel if your boyfriend goes to celebrate his ex’s birthday without telling you, but them 3 days after he tells you the “truth” that he really did when to that birthday celebration, crying and saying everything that happens

So the day of his ex birthday “mom of his twins” I knew something was wrong when he said he was going out “we live together “so I asked him how weird that his friend were at the at party and not him 🤨-how do I know? I followed his ex from a fake account and she post pic with them (not with my boyfriend) and I asked him oh that’s weird that ur friends are there and not you and he mead me feel stupid saying that I don’t trust him because I followed her from a fake account!

BUT NOW HE COMES CRYING TO ME SAYING THAT HE DID GO? And that he doesn’t feel good because he lied to me.

Ladies always believe in you, when there’s something wrong THERE IS SOMETHING WRONG !

WHAT DO FUCK I DO?
