Help a girl out... need advice

I’ve been with my man for over 4 years and we have been through hell and back together. He stood by my side through countless things, and I, in no way, want to diminish that by what I need to say. BUT after 4 years our relationship hasn’t progressed at all (other than emotionally)... and when I say that I mean it. He lives in his parents spare house at 28, finished his bachelors degree but refuses to use it and works part time as a security guard... I own my own townhome, work full time and I’m in graduate school... he swears up and down he’s making an effort to help us progress but can’t get interviews... he has also been saying this for a year. His parents are also completely overbearing and control his life because he lives in their extra home... I want to give him the benefit of the doubt but it’s getting more and more frustrating, especially when he acts off when I bring up living together, marriage, kids, etc. I get he wants to be financially secure, as do I, but it comes to a point where it seems like excuses after excuses. I love him so damn much and I understand many of the reasons he has for his actions, but how long do I continue to put my needs and wants on hold for a future that may or may not happen? I’m sick of watching his parents treat him like a child and I’m worn down.

I don’t need negative comments... just genuine advice. I’m so conflicted and sad by the whole situation. I could give all the advice in the world to other people, but when you’re heart is in it, it completely changes things...
