I'm actually thankful for the experience. It showed me early on what I DIDN'T want in a man. If I hadn't learned then what was important in a future husband, I wouldn't have been so incredibly blessed with a fabulous husband that I love to distraction, two wonderful kids, and a life of inner peace (despite too many "rollercoasters" in recent years). We're coming up on 10 years of marriage, and I am still his "everything."
Not surprisingly, the ex-boyfriend still hasn't married.
I can relate to that.
I also know the verbal abuse can be just as bad. It's often a precursor to physical abuse, as well. (I learned later on, from a friend of the family, that my boyfriend's dad had been verbally and physically abusive to him when he was growing up. I wonder what kind of relationship your ex had with his parents.)
I'm glad things worked out for you. Hopefully your ex-boyfriend will get a counselor one of these days and get a grip on his problem.
