I didn't include those reasons in my personal statement, but if it comes up in the interview (please, please let me get some interviews!!) I'll mention it.
I'm from Houston and would love to get in at either UTH or UTMB in Galveston. My husband has a really good job here and my entire immediate and extended families live here. I have a really good support system, and would hate to lose that if I have to move to a different city. But I would if I had to.
But, that being said, I am married and it might look different to the adcoms for the situation to involve a boyfriend. I'm not saying a boyfriend/girlfriend relationship can't be as serious to the couple involved as marriage, but the adcoms might view it that way.
