he didn't want me to get pregnant

So me and my husband just got into a heated conversation and he let me know that he stopped nutting in me earlier in our relationship because he didn't want to get me pregnant. I'm not really upset, but I definitely feel as if I have him trapped in something he didn't want. He's leaving in just a few days for his year long deployment and I'm thinking about getting an abortion while he's gone. Not only will I be trapping him but I will also be stopping what I want to do for myself which I didn't plan for. I thought that we were trying to get pregnant, but now I find out that this isn't even what he wanted. I just need some feed back because I'm so confused.. I really don't want this baby anymore especially if I'm the only one that wants it. This was such a surprise, I thought it was planned by the both of us, I thought we both wanted this... I guess not, I just wish I knew this before I made it to 10 weeks..
