what kind of man does this? a man who is only concerned with his wants and needs.
was he thinking about you and how you would feel when you finally found out? was he thinking about you and the potential for pregnancy when he began having sex with you? what he thinking about you and hurt you would be?
was he thinking about his wife? was he thinking about their child together? was he thinking about how hurt she would feel when she found out?
the answer to all of these questions is NO. he was too self absorbed with his own selfish needs and wants.
i would caution you to think seriously about even thinking about a future with him, can you ever trust him after what he has done. men like him will use every trick in the book, lie, lie, lie, and then lie some more.
i would recommend finding a good personal therapist, as you are going to need some one to speak to, a shoulder so to speak.
i would caution you to see him for the man he really is and NOT the man you want him to be. you can not change who he is - and neither will your child. only he can change who and what he is.
please take care of yourself, i am so sorry that you have found yourself here.
