Single Mom

I'm currently pregnant with my first baby. It's a blessing but I'm definitely not in love with the father of my baby and wasn't too happy when I found out. Before I found out I was pregnant I told him things wouldn't work out between us. I just wasn't happy at all and felt forced. And he was so in love with me. I just didn't feel the same. And about a month after found out I was pregnant. He knows about my pregnancy and is willing to be there for the baby. I just in reality have become so depressed over this because I don't want to be with him in anyway. He suggested marriage and I denied it 100%. I'm so unhappy I don't know how to be excited. I feel like it's so wrong for me to feel this way.. I don't know what to do. He's so clingy even after I tell him how I feel. I feel suffocated by him. Like he still tries to be romantic with me and I just don't want it. Like he thinks I'll be with him because of this baby. I feel trapped...any advice? No rude comments please.
