I need to tell my fiance I feel borderline abused because for these last few months her bipolar has her yelling at me and it's eroding my self esteem
Are you sure you want to tell your fiance this?
Yes I can, I usually don't want to leave the house any more because of it.
if your girlfriend needs medical or psychological help, you should confront her about it in a positive and uplifting way. Don't make her feel attacked, as that will push her further away from you.
I disagree with you. I think I should make her feel attacked to make my point. I should also make her mad by dismissing her emotions.
If you make her feel attacked she's just going to retaliate. If you really want her to get help with the least resistance than try talking to her calmly to get her to see your point. She'll be more open to wanting to change if she can empathize with how she's making you feel.
