Should I tell him there is a question of paternity now or just wait since babies due next month?

Hmm..tough one since its all almost over and you will have an answer sooner than later..i guess my question is who are you with now? Are you still with the new guy or are you not with anyone? If you are with the new guy and if so, does he think for sure they are his babies or does he know there is a good possiblity it is not his? That being said, I guess it is really up to you as to what you want to do as if he is going to be more stress to you (the ex) then just wait, you don't want to stress yourself out right now at the very end fo the preg esp with twins! If there is a chance you will get back together, he will be supportive or be there for you in the time of delivering then go ahead and tell him but be sure to make him understand you are unclear 100% and won't have results for a week after they are born so he isnt mis led. If I were you I really dont know what to say I would do, I would try to prevent this situation from happening but since it did I guess its really up to you since either way you will know one way or another in a week or so IF I had to pick one to tell you to do I would go ahead and tell him now, let it process with him and maybe he can use some time to figure out his feelings. Hope I helped somewhat lol
