My ex husband keeps inviting me to go to India with him and his family. As much as I've always wanted to go, I know it's a terrible idea....I think he'd probably 'try something' with me, and then get mad when I don't reciprocate. People don't just invite exes on trips so you can 'hang out' as friends, please.
Also, I don't think my bf and his gf would be very pleased about it.
