Is this important to a Taurus

Dealing with a Taurus man who I met as friends only to find out a couple months in that he was still dealing another woman. He met her last year and while dating she moved. They didn't move into a committed relationship because of his choice. he has given her a deadline of moving back but she had not an she (a cancer) says she can't for whatever reason. So my question is how did he develop any feelings for me? He claims these things means something:
Taking time from the person he cared for first
Driving 50 miles to see me in his mom's car since his isn't working
Taking time to talk things through with me
Continuing to see me when he is frustrated with me

I do acknowledge his sacrifices especially saying he is done twice and going back on that but I wonder if he really has went back on it if he is still pissed. I told him doesn't sound like he has given me a chance as long as he just reverts to he is done. i have done some stupid stuff thinking it is over and being really hurt. Right now he added me back to one social networking site and but no fb and blocked me number and just says he will unblock it once he feels comfortable again. I was wrong so I can accept that but I have been fighting for him and I am not sure why.

THE FIRST CUT OFF: He said I wasn't a good friend so I told him how I felt about the girl who moved. He wasn't mad about what I said but that I should have said it sooner. He did not take it as me being jealous ironically he took it as I really care for him deeply and don't want him to be hurt, which is true. I don't like how she treat him period. I think that he thought he could cut it off and come back later once he got closure from this other person. The problem is once I give up that is it. We spent the first 3 months wondering if one was going to cut the other one off.

In spite of it all he will still answer or call me back and talk to me for hours. he got to the point where he would not put any effort into me and him and had completely given up but he finally said he will put some effort in. he has accepted some things as just being me and will try to not let them bother him. This was because I asked what i could do to fix it and he he said nothing. I asked him to clarify and he said "just don't get on my nerves". A conversation ensued and I am going to try not to bother him with certain things and he is going to try to let his irritation settle. HAVE I DONE THE IMPOSSIBLE? Getting him to keep going! AND What now?

My plan is to give it some space since we are in agreement to work on it and he has a lot of problems outside of me in his personal life and professional life. Living with moms and two kids, no car.....it is a lot but this forum has helped. Trying not to call for a week....

Another big one he quotes is that he always tells me everything, He truly does give me a whole lot of information whether it be who he is going to kick it with or go on a date with or what him and the other lady is doing, a party he is going to, what his relationship was with others and what is going on now.
