Advice Needed.

Long post. Sorry.

After many years of eating disorders, I've been okay for a few years now. Since being with my partner, also my unborn child's father, I have had the urges to go back to my old ways for many reasons and the only thing stopping me is being pregnant. The reasons for feeling shitty are a long list including the fact that his "type" is more... short, skinny, blonde or redhead with no boobs and I... am a tall, curvy, raven haired girl with big boobs (And now pregnant). And though I generally like how I look, I don't like how I look for him. In addition to this, it seems I initiate all the sex. For every 10 times, he'll initiate 1. He's never in the mood, or too tired, etc etc. but I really feel like it's me. It's killing me. I just don't know what to do.

Also. No bashing. He's a good guy.
