I'm a 39 year old man who is having a relationship with a 17 year old. She'll graduate Friday, so I'm not worried about any of the sexual conduct laws. That variable goes away shortly. I'm not worried about age of consent law either. We have both done extensive research on this and we are confident in our understanding that age of consent begins at 16. I just recently found out that state laws on age requirement and sex are NA in Michigan. So here's my question....I have a child with my ex-wife. Can she legally keep me from having my girlfriend with my child? My girlfriend is going to be moving in soon, though we are not calling it that right now. I'm thinking about my job here. People may think it's weird, but we are very much in love and we have a very responsible relationship. This is not about lust and passion, it's about a whole lot more.
