Yes I have researched co-dependency and my problem is that I redefine my boundaries to avoid confrontation. Luckily I don't have a lot of the symptoms. But I am a peacemaker and will sacrifice myself to make peace. Upon realization of the boundary issue, I recognized my faults (not having boundaries), recognized my boundaries and left my husband. So yes, you are right. I do hope that upon this realization I will continue to hold strong to my boundaries and stop this cycle of allowing people to cross them.
Thanks.
