Firstly I hope the following question does not sound sexist as I am not intending to sound that way I am just looking for some advice from a woman's perspective.
Can really bad periods cause major relationship problems? I ask because I was in a 3 year relationship up until the end of 2018 & my ex had a habit of breaking up with me at least once per month as well as occasional verbal abuse & insults especially during arguments & the break ups. Some of the stuff she said was very cruel & its left me feeling really low. I had to remove myself from the relationship because it was exhausting me & I felt as if I was walking on egg shells always preparing myself for the next break up.
She had really bad periods & she occasionally said that this is why she broke up with me & was sometimes nasty. She was also very needy & often accused me of cheating when I was 100% loyal to her & gave her no reason to suspect me. I read something today about PMDD & wondered if maybe she suffered from this. As I said I am really sorry if this may come across as sexist but its a genuine question as I am going through a bad patch & trying to figure out why she treated me in this way. Thank you.
