Will he ever graduate? He's been going to college for 8 yrs now...Help!?

My boyfriend and I have been together for 2 years now. He is almost 27 and has been going to college for 8 yrs now. He spent 4 yrs in JC, 3 yrs in CSU so far. AND He seems to be no where close to graduating (I am 22 yrs old and I'm getting my BS in June!) The school loan is already 30k now. I know it doesn't seem like a lot but he's also qualifed for free $4000/yr financial aid from the government due to low income. Yesterday, he told me that he might switch his major because computer science is too hard for him. It seems like even now he doesn't know what he wants and that he chose computer science only because they make a lot of money. I love him so much. We were thinking about getting married after I'm done with grad school (which is in 2 yrs from now)...but I have a feeling that he won't even be done with his Bachelor degree yet. I dont know what to do... Please Help!
