Men lose interest in their girlfriends for a bunch of reasons. Some of those reasons are real and understandable. Others are just because people suck sometimes, and there is nothing we can do to change that.
The key is understanding how we can carry on, loving ourselves, and just waiting for the person to come who accepts us for who we really are.
Here are some reasons why your boyfriend lost interest:
He likes the chase
The pursuit is oftentimes more fun for men than actually having a meaningful relationship. Chasing tail, so to speak, is a pastime some people commit to rather than people. He will lose interest rapidly once he got the goal – whatever that goal was. Again, this is not your fault, and you cannot change a man who loves chasing women.
You are clingy and insecure
As a result of number one, you change. It may be unconscious, but you become clingy, in constant need of reassurance, or volatile, because it can only be the future for you two. And you need to know that the image is going to happen. The insecurities make you look like a crazy lady.
For men, insecurity is a frightening thing. As is putting others down to make yourself feel better. In his eyes, you are no longer seeking to learn about who he is, only what he can offer. For that reason, he will lose interest and not be able to tolerate the relationship anymore.
