Boyfriend is a workaholic

[candelight]

Hello everyone, my man of 4 1/2 years is so consumed with his work it is crazy. When we met, yes he had 2 jobs then but we were seeing each other more. He is a correction officer, daycare owner, and recently took on a new project which is a real estate developer(oh yeah, kids too). Sometimes I think he is working so much because we have been having problems and he uses work as an excuse, but he said that is not the case. He retires from corrections in 2011 and he says he wants to be set for his retirement and close the daycare and live off the money he gets from his property. Which I think is smart, but sometimes it is so hard because I miss him and it hurts when he is not around. He spends the night with me when he is free, but then sometimes I won't see him for 2 weeks. Again as I said before, we are having some problems so I'm not sure whether I should blame it on him working or what is going on in the relationship. I spoke to him about this and he said he has to keep working like this so that he can be comfortable. I love him and want to stay with him but it can be really challenging and frustrating for me, and in the end I end up resenting him and when we do see each other my attitude is negative. Guess that might be a reason I don't see him much as well. I really don't mean to be this way. I want to support him and be there for him but it is not easy. We have been together for so long but we both are not ready for any major committments now. Living together, marriage. I want it evenutally, but not now. But I still want him in my life as a partner. Someone please advise! I feel like I am stuck sometimes. Thank you.
