I think that if you've reached the point where you would rather stay home and prance around the house in a mini skirt and heels than attend a relative's wedding and interact with people in men's clothing, it's time to take a look at yourself and your mental condition. That's just not right.
Where many crossdressers get into trouble with their spouses and families is getting so involved with dressing that they exclude other activities and other people.
To be mentally healthy, you have to be able to turn it on and off as appropriate. I am about to leave on a two week "vacation" where Krisi will be left behind. That's fine, I will enjoy myself as Homer and Krisi will come back out when I get home. If you can't go a few hours without dressing, you have a problem.
