Hi sickandtired and Welcome! It's tough to stay in once you know it's no longer the truth as they claim. You need to think about what's really important to you because of your family.
I do agree with you that JWs have some good values but then, so do many people outside the religion as well. They do not have the market cornered on this. My policy with my family has always been to agree with their right to their religion, to point out fallacy when they try to preach to me, and to live my life as an example that contradicts their 'worldly people are evil' mantra. So far I have been able to maintain a connection with family, albeit disconnected, sometimes strained, and stilted. You cannot have a normal relationship like other people do with their family when one of you is a JW, and the other is not.
