Someone help please

First of all, do not jump into another relationship just yet...if this other guy really wants to be with you, he'll wait until you've dealt with this current breakup first.

So, what you're saying is that you got pregnant and he dumped you because you gained weight? Also, he's been cheating on you?

I know it hurts right now - 16 months is a long relationship, but surely you can see what's wrong with this boy. You deserve better than this and so does your baby. The guy is a deadbeat, and once you've had time to work through all these feelings, you'll be able to see it more clearly.
Cry if you want to - it's part of the healing process. Just take comfort in knowing that it will get better...all you have to do is make it through one day at a time.

Once you do get yourself back on your feet, tread slowly - you don't want to jump into another relationship just because it's available...wait for the guy who gives you goosebumps.

One other tip - get child support payments...this boy needs to take care of his responsibility.

dang thats screwed up just re-evaluate and move from there
