Why I think it will work...

... with a little help from a very logical article (just evidence of common sense):
Article from MSN Lifestyle

"...it is virtually impossible to give something that you don't have and self-identity is finished forming around the 27th year of life. How can you get married and give of yourself when you marry early and your self-identity still hasn't formed? If you get married (or something similar) before your identity as a separate autonomous human being has formed, you interfere with this process. And even many older adults still struggle with who they are.

"... If you are depressed, anxious, angry, insecure, jealous, picky, controlling, passive, obsessive or compulsive, someone else (i.e. your partner) will pay the price for your behaviour. This will interfere with the possibility of a good, healthy relationship.

"... Another area of compatibility to consider when choosing a mate or deciding to stay with one, is the issue of lifestyle. Do you like the same movies, restaurants, types of vacations, healthy style of conflict resolution, money management, long-term goals, child rearing style, etc? There is a lot of compromise in the best of relationships. Each time you compromise, one or both of you get less of what you want. After a while, if this is excessive, it can become tiring.

"How about personality? Are you similar in character, curiosity, vitality, intellect, appearance, sexual passion, artistic interest, adaptability, self-concept, moods, communication, kindness, autonomy/closeness, humour, sociability, energy, ambition, education, spirituality, values, morals, and ethics?

"This list only scratches the surface but it is a guide for you to consider. The greater the similarity between two people - including emotional health and maturity - the better the chance of a relationship working long term."

Jonathan asked me a question yesterday. I think a lot of what is listed here applies. He's right about the one thing that is beyond my control!
