Hello- I used to post here a lot, it's been a while! I got divorced 5 years and ago and have been dating someone for about 4 years now. We moved in together last fall. He has 3 kids (who don't live with us- they live out of state). He takes them on a vacation every summer for 2 weeks. This summer he asked me to come, but asked me to split the cost with him. I think it is strange, he does this same vacation every summer. If anything I feel I should pay for 1/5 of it, why should I pay for his kids too? Am I being unreasonable? Thanks!
