Presumably you have reasons. Some male(s) have hurt you or let you down or both. I can give you some general advice, but not knowing the exact reason makes it impossible to be specific.
1. Unrealistic expectations. There are no infallible men. Put a man on a pedestal and he will fall off, likely landing on top you and crushing your hopes and dreams
2. Abuse. Some men really are insensitive jerks and belittle people at the drop of a hat. Physical abuse is wicked.
3. Men are not women. We don't think like women, our interests are entirely different, we are task oriented and we can be less than subtle in expressing our maleness. If a woman tells me something, I want to know what she wants me to do about it. If the answer is "nothing", then very likely I'm not interested in the conversation. Women are inclined to take offence at that.
Most women respond with hurt and then unforgiveness. This is the root cause of most relationship problems. Unforgiveness is often the result of wounded pride. Whatever the cause, we have no right to harbour unforgiveness. It affects our fellowship with God and poisons our attitudes to people. If unforgiveness is not dealt with, it festers and ends up in bitterness and resentment. That can lead to arthritis, sometimes crippling.
The good news is that you do not have to remain bound by unforgiveness. As long as you are willing to forgive, God has provided the answer. The following article is quite long but well worth reading. It can change your life if you will take it to heart.
