We got together 3 mnts ago and were in love talking about a future to gether,then he finds out his ex has a baby and is saying its his,he says he needs to sort his head out,but I've had no contact for over a week,what should I do!

I think u should wait

You are trying to answer your own question??

He has a very serious situation in his hands right now, that could affect his entire life.

He needs time to sort out what is happening with his ex girlfriend. He will need to establish paternity, pay support, learn how to be a father if its his, and devote a lot of his time to his baby. That is the right thing to do.

The baby has to come first.

When the dust settles, you too will have had time to consider the consequences of being in a relationship with him. Do you want to be a step mother for a good chunk of your life? Are you ready to take on such a huge responsibility?

I would let things take their course. You will know soon enough what your relationship with him will entail.

Back off and let him work it out himself. You can tell him that you're there for him if he wants someone to talk to, but that's it. If you're meant to be together, he'll be back.
