I've been with my guy for about 4 months now, and just found out that his ex-girlfriend is about 7 months pregnant. He knew she was pregnant, but says he didn't mention it to me because there is a 1 in 3 chance that it's his. Now I don't know what to do - I do care about him, but feel like he wasn't being upfront. What would you do?

You better hold off on any decision until he finds out for sure whether its his or not, and the bigger issue is not him being truthful, but that he left a female that has a 1 in 3 chance its his.

Get all the facts and act accordingly, but don't get in deeper than you are as no telling what else he didn't tell you.

He should have told you when your relationship with him, was getting serious. He had known for seven months, and didn't bother bringing it up, doesn't speak highly of his character.

His math is probably wrong too.

You ask what I would do. I would consider that because the relationship is still new, I would not further commit until he knows one way or the other, if the baby is his.

If the baby is his, consider seriously what would your future with him be. He will be financially and otherwise, required and expected to play a very large part in his child's life, for a very long time. That will also involve his ex, and future complications with more children, custody issues, etc. etc. etc. His child will (and should) be his first priority, over everything and everybody else- including you.

If the baby is not his, I would still proceed with caution. I would personally be very uncomfortable with the fact that he somehow neglected to even mention that he could be a father in a few months, regardless of 'the odds'. Had he been straight, sooner, with you, you would have had the opportunity to either walk, or prepare yourself for what may or may not be. To be blindsided with this was just not a nice thing to do.

I think she is cheating him.So,keep distance from her.
