Given the information available at hand (the assumption that you're a family, as I'm not privy to whatever info RP seems to have), I also agree with Ari.
For me, one of the biggest reasons I wanted to marry my husband is to make a clear, conscious commitment to deal with every problem either one of us has TOGETHER. When you're family, there's no such thing as "other real life drama". My husband is very much a part of my "real life" and any drama that happens to either one of us is family drama, not personal drama.
This may be one of the best indicators of whether or not you truly consider someone to be family. It's easy to be close and lovey-dovey when life is good. The real test of any relationship is, how does it look when life is not-so-good?
Before we got married, we dealt with deaths in the family, kids running away, job losses, moving cities, bipolar and/or depressed mothers, personal anxiety, self-esteem, selfishness... And every issue that we dealt with together made us come out stronger both as individuals and as a couple. It never occurred to either one of us to end the relationship on the grounds of life being hard. We saw the other in pain, and only wanted to help.
Gralson: my husband (works out of town).
Auto: my girlfriend (lives with her husband Zoffee).
The most dangerous phrase in the English language is "we've always done it this way."
