Hang in there and you are right you will be fine.. I was in the same boat as you 2 years ago, I was with a guy whom I was friends with for years. We had a FWB relationship to start, but my feelings started growing about 6 months into it. I tried to break it off a few times but he kept coming back, so I though he must care about me. A year and a half later I became pregnant at the ripe old age of 38, talk about a shock to the system. I already had a 11yr old and he had a 10yr from a previous marriage.
I knew he didn't love me even though I did him and he begged me to get an abortion. I didn't know what I wanted and was scared to do it alone again. I didn't want to have another child with an absent dad, so I made an appointment for an abortion. I felt the same feelings as you, I was very depressed and cried constantly, with no support from him. He would still come around, but we never discussed me being pregnant. He didn't even offer to go with me to the clinic. I received a phone call at work 3 days before I was supposed to have the abortion, it was the clinic telling me I had to reschedule for another time. I was broke down sobbing, knowing then and there that was my sign, that I could not go through with it. When I told the EX, of course he flipped, but I didn't care it was not his body going through all of the changes.
I moved away and told him that he doesn't have to be involved if he didn't want to. He ended up being a great support throughout the pregnancy and gave me false hope that he cared. Today my beautiful baby boy is 19months and I could not imagine my life without him. He is such a joy and I feel blessed to have him and think back that I almost threw him away because I was scared. The EX is involved in his life a little bit, but has moved on and is with another woman. I got the best part by having my son and know I am in a better place without the EX and all of the drama that came with him.
So take good care of yourself and keep your chin up! You CAN and will do this and once that baby is born, you will see that it is all worth it! Take care
