It goes across every economical situation. I know somebody who was married to his wife for 13 years, just kept telling himself he was unhappy. Seperated from her, got involved with me, gave me HPV, then on top of everything else, got involved with his business partner.
In the meantime, he got found out by his wife when she caught them together and had the strength, courage and love to go ask him to come back home. He did. He got her pregnant.
Now, he has divorced his wife and their baby son is going to be born in six more weeks.
I talked to him yesterday and I cannot understand how he could be throwing away not only his wife but now his little girl and unborn son. He says, "I just want to be happy." Happiness does not come at the expense of people who love you.
He, himself, was born to his mother when she was 16 years old and raised by his grandparents. Maybe they just overcompensated and gave him everything.
We all have hard times in our lives.
I know I had a terrible first husband. I kept my child (didn't know anything I could do but do that and I am glad for that decision. It was never an option. I was married and it was our child.)
You sound like a very intelligent young woman. There are lots of options for you. Please, if you love this person, try to get him counseling. If it is not love, make a safe place between the two of you and your little baby.
Good luck.
