Why men choose to leave

I am hurt, my ex used to do everything for me he even would drive all the way to the airport to pick me up if I called would drive one hour just to see me, he would pick me up off the ground so I wouldn't slip on ice.

Along the way he stopped caring, I was four months pregnant he told me that he wanted to break up, I was on my own he didn't care that it was his first born or that I had no home no job or car no food no ride to the doctor. He just didn't give a fuck literally told me he wanted to find the perfect girl and start a family with her.

The thing is his dad has 10 kids he did this to so many women lied about wanting a relationship got them knocked up then ran away and he told me how his dad always choosing pussy over family and him hurt him how he was always cheating & leaving him.

The thing is he wants his dad to love him so bad.

Well he broke up with me and ended up with someone like his mom a single mom with three kids. He went to go live with his dad while she raised his brothers he had been looking to repeat the cycle of his past like those memories still hurt him.

I'm so confused, I never thought he would be this monster.

After years together all the planning for the future gone, now he's with someone and I'm hurt like why didn't he care enough or try.

Why do guys give up and see women as things
