I was listening to the Radio this Morning...
I have quite a few lesbian friends/co-workers. Two of my best friends are the parents of my Godson. They did the whole artificial insemination thing. They changed their last names to be the same, have done the whole estate planning thing, have worked out their rights regarding their Son through their estate planning etc... They are also financially stable. They have done commitments ceremonies and have traveled to states that allow marriage and done that, etc... I think that their age also has a lot to do with it. They met in their mid thirties and are now in their forties. It also helps that their friends and family have all accepted it and have embraced them.
They are stable over-all and I would be shocked to see them split but they are the exception to the rule.
Most of the lesbians that I have known have virtual turnstiles at their bedroom doors. They are always moving in with each other, fighting constantly and then moving on to another bad relationship. I sometimes think that their changes in appearance hurts things. My Godson's parents are still quite girly but most of the others that I know start trying to look like young boys. One that I know had hair down to her knees and cut it off shorter than mine. It wasn't two months before she and her girlfriend were at each other's throats. If you are a woman and want somebody who is attracted to women, maybe, you should try looking like one. Just my opinion.
I notice that a lot of the lesbians that I know have financial problems as well. I imagine that a lot of this has to do with the fact that women, often, make less money than men. Nearly all of the gay men that I have ever met have had plenty of money and most of the lesbians that I have known are the opposite. As with heterosexual couples, the lack of money is going to start lots of fights.
Another problem that I see but not from folks that I know is that arguments in gay/lesbian couples get physical. MOST of us men are taught not to hit women. Our arguments with women, therefore, don't get physical. It is not considered to be as bad to hit those of the same gender. I can imagine that some arguments get way out of hand. This kind of atmosphere is also going to end things more quickly than otherwise.
All that you really have to know about why lesbians have relationship problems is to work with a bunch of women. They, for the most part, can't help but fight, backtalk, back-stab, and argue and they want everybody to join in.
