Relationships

Guys, Should I stay or should I go?

My boyfriend of 4 1/2 years, is 27 and still living at home. This wouldn't be such an issue, except that he hardly has any time for me because of living at home. His mother is in her 50s, and stays at home all day. When I went to visit them in the beg8ning of the relationship, I noticed that his mother is basically bedridden. She is physically capable of things, but stays in her robe, watching TV all hours of the day/night. He has very little boundries established as well, as he is not allowed to shut his bedroom door. His mother will wander in any time of the day or night, with requests for food, or a chore. Once, I woke up to his mother and father standing over the bed, watching us sleep. (They both allowed me to stay over, and knew I was in there. Also, his father is a trucker, and comes home once every other month, for a week at most. This leaves my boyfriend to keep the house running, and care for his mother. The only time he can leave the house is when his father does come home. I asked him why, and he says his mother has panic attacks if left alone for more than a few hours. This means, that due to the hour drive between is, he only sees me once or twice every couple of months. (For a few hours at most) then it's back to mommy. And true to his word, he has cancelled dates, been late for work, and even walked out of a restaurant after we ordered, just because she called and said he needed to come home. When we first started dating, I was ok with this. But 4 1/2 years in, after watching most of my friends relationships progress, I'm actually surprised he hasn't realized how he's hurting me. I feel like a cheap hooker, not a girlfriend. Please help
