Hello Chickpea,
I went through the same thing, as did many others here...in fact for a while we had a thread going called "Pregnant and doing it on our own", which I guess you could find if you did a search (I don't know how to make a link to it)!.
DS is 10 months now; he is a lovely, lovely baby and we are comfortable and stable.It's taken me quite a fight to accept that his dad has rejected both of us (he messed us around a lot), and just as much effort to realise that the man is a total disaster area,and if he'd been around would just have pulled us down.
If I had to do it again, I would have made sure I had a warm, cosy, safe home ready- instead, I foolishly thought I could go on living on my boat in the depths of winter, which left me very vulnerable. Do you have a good place to live?
I wouldn't be surprised that your parents don't seem able to accept the emotional impact of your situation- IME most British people, especially of the older generation, don't "do" emotional distress. Although mine have been practically very supportive and non-judgmental, several times I have caught them rapidly changing the subject as I walk into the room, as they think "mentioning it" will upset me! As if I wouldn't think about the subject otherwise!
But they have been great otherwise, and I stayed with them for the first 3 weeks after the birth. That was a lifesaver, and I would recommend it if you can.
I've got to go now, but do keep posting, and be aware that it does get better, and you have to focus on making a comfy, easy nest for you and the baby, and pull in as much support as you can.....
