Help?! Torn on what to do!

I just found out yesterday (1-6-17) that I'm pregnant. I believe I'm around 5 weeks. My boyfriend and I are split on what to do and I feel alone. He is leaning towards wanting me to get an abortion and I don't know if that's what I want. While he says he would be supportive no matter what, I feel alone in my wanting to keep it.

It's difficult, because we live in his mom's house while I'm finishing up school. I graduate in May and again in December and his job is alright but definitely could not support a family of 3 living on their own. I don't want to live here forever and I don't want to be more of a burden on my MIL. I feel like I'm ruining our lives and Idk if I feel this way or my boyfriend has made me feel this way.

I'm so torn and I have so many thoughts and emotions swirling around in my head. Please give some insight if you have some. On one hand I'm scared and disappointed, but I'm also excited about all the wonderful things that come with pregnancy and motherhood. Thanks for reading.
