"Has anyone else gone through this and how have you overcome the bitterness? It's eating me up."
Yes, I have. To be honest I still sometimes feel it. I know I M fortunate I am married to a very nice, hard working man. He loves alone for at least a decade before we married so be had never looked to me to be his maid.
I'm working hard to ensure my 7 year old son Doran't grow up to treat women badly and I must admit it is not easy to counter the messages on society about men being superior. So I don't blame mothers for their sons. Or if I do I blame parents for their children.
I personally do compartmentalize people! But not into make and female. I go with people I trust/people I don't trust etc. A lot of new men I meet might be in the people I don't trust category until I feel I can! So I guess I am just cautious around people, especially males.
I don't blame all men fit rape.
I'm lucky I married a nice man. I know a lot women have had appalling relationships with men and it is not their fault.
I think the best thing is to get more aware of the issues and to look after yourself.
If your dp/dh is doing things you do not like, challenge him (if safe to do) and evaluate if this is the relationship you want.
I believe/know there are some good men out there and being single is always an option so you don't need to stay in a relationship that makes you unhappy.
Good luck
