There can be a lot of wide-ranging reasons why men would dump women. Some of these reasons could be for real or just an reason to cover up why they really left. Commitment is a big one; many men do not want too or are just not prepared to commit to a serious, long term relationship. Perhaps they want to meet other girls or just have the liberty to come and go as they please.
Some men will claim they felt they were being pressured to make a commitment which may be the case or not. They will use this as an excuse to break up with their girlfriend. It could be they had no intentions of staying with them from the beginning or there is something else that caused him to leave.
The girlfriend being overbearing or nagging could be a reason. Being overbearing can be a legitimate reason if she does this in front of his friends or out in public, no one likes to be belittled or put down. Also a women who has her man on a short leash is not going to get much respect in the long run in the relationship.
If your relationship started out great but is now failing, you need to find out what went wrong if you want to save it. There must be something about you that attracted him in the first pace. Find out what it is and put it back to work, could it be you have let yourself slide or maybe you thought you finally got your man and became possessive of him?
