If you do have a child with a man like this, only do it with your eyes wide open.
As he is prepared to be dishonest with you and hide important things from you, that upset and disgust you, you have to assume this will continue.
so there is a pretty big chance the relationship will fail. Having children always seems to put the problems in a relationship under the spotlight and makes them worse.
You then have to think whether or not you could cope not only with the practical problems of parenting without a partner - do you have back up nearby, what if you are ill, etc, etc but also the emotional difficulties of arranging contact/continuing a relationship with someone you may wish was well out of your life.
I wonder whether the real issue in circs like this is whether or not you really want a child because you want to love and nurture that child and experience the highs and lows of forming a relationship, guiding a child into adult hood etc, etc, or whether what you want is more the 'dream' of the happy family with mummy, daddy and child.
I do think you have to distinguish between the two. I got confused between them and ended up dealing with the aftermath of trying to manage a 'relationship' with my daughter's father after separating which is not great fun.
I would probably have been much better off remaining single and looking at adoption/fostering options.
But whatever you do, think really carefully about it and make sure your eyes are open to all the possible issues.
