Love help?

All right i have a problem. My ex has started calling me again, to get back together. We broke up a couple of months ago. I broke up with him because he could not get a job or anything. But now he has one. But i have a nother boyfriend since then that i really really like maybe even love. I still love my ex cause we were about to get married. Now he wantes to get back together and i think i do to. Plus i might be pregnant with his kid because we had before we broke up. So can anyone help me figure out what i should do.
