Yup, as always I agree with nikki there!
And to add to this, it's only my opinion and experience, but most 22-year-olds dont go out with 15-year-olds, and when they do, it's not always for a good reason! I personally know some older guys that are going out with younger girls coz first, they cant find girls their age to be interested in them, second, they think it's much easier to get with girls that are at their teens becoz of the lack of maturity, third, younger girls cost less!
It might not be ur case, but like nikki said, it's best to take ed's sis and mom's advice and leave ed alone, if he truly loves u or wants to be with you, he will keeps coming around, but if not, then u know.
Ur baby's daddy doesnt seem to be a very good father either, I mean he questioned you and baby, it shows how much he wants to be involved or take the responsibility. So ...
I am sorry for being a bit negative, but u should consider the worst senario
