yes, i saw that when it first came out, great movie! Courageous is also a great movie with some similar things going on. my men's group at church has done several studies on series like that so if what i said sounds familiar then that's probably why! one thing you said, whether he loves you back...as a Christian my thoughts on love are biblically based in that God is love and all love starts and begins with him. so, if someone is detached from God they are losing a really great way to channel love into their life. again, i'm not judging or even saying that non-believers cannot love as that would be incredulous. i'm just saying that if you draw nearer to the source you can get so much more out of it. my MIL dealt with a failing marriage for 19 years doing exactly what you sound like in caregiving, submitting, loving without any return in kind, etc. and the man was so bullheaded he couldn't see the problem. either that, or he did and chose not to do anything about it. it is a sad and all-to-common issue that so many suffer through, i'm sorry you are having to deal with it.
