Should I terminate my pregnacy?

I'm super confused as to what to do. I'm 33 years old, and I'm about 6 weeks pregnant. I already have a beautiful little girl with my x-husband. I now have a boyfriend who also has a daughter. I've been with him for about a year, but have known him for many years. He's a great guy and an excellent excellent father, however, although I love him, I'm not "in love" with him and am almost positive I can't see myself with him long term, but I'm not sure. He really has no financial security, he's unemployed (but is always working on something in the garage or on side jobs for cash) and frankly, little things he does, like his eating habits, m amount of smoking, and farting every 12 minutes drives me nuts. I talk with my x-husband almost everyday and he would really like me to abort the pregnancy because although he thinks my boyfriend is a really great guy and a huge help to me, he doesn't see us together long term. And sometimes we throw around the idea of getting back together. What do I do?
