Please help me with some relationship and sex advice?

I have been with my partner for 2 years and prior to being together we were good friends for 12 months. I love him to bits, I really do. but it's like we're best friends now and not lovers. I'm pregnant with his child, and have never had children before. I am 6 weeks. He is wonderful and we get along so well. But we haven't had sex in a few months. It's not him, I know that. It's all me. I don't get turned on anymore. Not by him. Why? I feel so guilty! I love him, but I am so afraid that I am no loner IN love with him. I know that I will never leave him, but what about our baby? Would it be like bringing a child into a loveless marriage? (We are not married as yet). How do I spice things up and feel the same way I did about him when we first got together? Or is it just the way things go after being with someone for so long?Please help me with some relationship and sex advice?
seek professional counseling, and then maybe get him to join u.Please help me with some relationship and sex advice?
If you really love him you would be wanting to have sex with him and he would turn you on. You need to seduce him to see if the sparks will fly again.
