I feel for you. My baby Ashton's father walked out when I was 4 months pregnant and I haven't heard from him since. It really shows the sort of person they are. Knocked me for 6 because we were friends for years before I fell pregnant (which he wanted at the time)
I have DNA testing next week because he refuses to aknowledge Ash, so I can't get Child Support, which I need at the moment (I can't work with 3 kids 4 and under ).
You can do it, you will be fine, it's his loss, just give bubs lots of loving and be honest when the time comes... "it isn't you it's him". Love bubs like 2 parents!
When the DNA test comes back as he is the father (which he already knows he is just being a jerk) then he can take that bit of paper and stick it you know where, the hell he put me through, the crap that has gone on, the negativity and nastiness, is not something I want around my beautiful, sweet baby boy
