Lonely in GA

I met my boyfriend on a dating site online a little over 2 years ago.He trains drivers for the company he works for and is gone between 4-8 weeks at a time. When he gets home time it is for 4 days. When I met him he was paying child support on his son which was going to graduate from High school within a year.

We talked about him finding a trucking job with local runs after the child support was over. Its been almost a year since his son graduated and child support stopped. His son is in college now and when he gets home time he goes to watch his son play baseball for college so our time is cut in half. I love his son and am not jealous of their relationship but I miss him too. When I mention him looking for a local job with more home time he gets angry and tells me that he doesn't want to give up the money he's making. Do I stay with him and be lonely or leave him? I'm starting to think he will never come off the road training and I will always be alone.

Any ideas or suggestions?
