Move on, but stay in his ass for child support. Get good legal representation.

If he wants all the benefits of being with you (the sex, kissing, holding your hand, romantic nights etc) but still says he needs space and doesn't commit to you then he is really just temporarily using you. Someone either wants you or they don't want you. There's no in between and should never be otherwise you're just selling yourself short. You say he's calling other girls and he says he need space... come on.. who are we kidding he just wants to have his cake and eat it too. He wants to hang out with other girls and canoodle with them while still keeping you in the background. Is this really love? Is that what you think love is? Does it sound like he loves you?
The answer is no. It's not love and no he doesn't love you if he wants to still be with other girls and can't commit to you.
Move on PLEASE.
