I am not saying that no one should go out with him. What I am saying is that the person who does needs to understand that his self-esteem issues are not her problems to fix.
The 'self' part of 'self-esteem' is very important. Feeling secure, happy, lovable, etc. all come from what is inside the person. Other people in the person's life enhance the feelings that already there. They do not and cannot create them.
While people do go through times of low self-esteem, it does not excuse how they treat others especially if they know how low their self-esteem is. I have found that many people who tell me they have low self-esteem do so to rationalize their own bad behavior. They play the 'poor, pitiful me' card in an attempt to make someone else responsible. However, they are responsible for their own lives, actions, and reactions.
You should not allow someone to make you feel bad about yourself so that they feel better about themselves. You can offer a hand up. Helping someone is a big self-esteem boost. However, you should not allow them to pull you down. They have to do the work.
This may be hard to hear, but he needs to develop his relationship with himself before he tries a relationship with another person.
I have looked at your other threads and there seems to be a pattern developing of you getting involved with males with self-esteem issues. Do you really want another boyfriend who makes you the scapegoat for his issues. If you look back on the relationship with the male who abused you, how did that relationship start? I am guessing you didn't see the small red flags before they became much larger. With this current male you have the chance to see those small red flags.
Tell me how do you feel about yourself? What do you do that helps encourage your own self-esteem to grow?
A boyfriend should encourage and enhance those feelings instead of making you feel like a failure because you didn't answer a question the way he wanted.
