So stepson 24 has now been here for 6 weeks he's openly stated he slept with a tinder girl just 3 days after breaking up even before he moved his things out ex- fiance's house & was dating 3 girls at once & has now picked the one with a house & money to be his girlfriend. I'm absolutely disgusted with his behaviour & lack of respect,  he has asked numerous times if she can stay over I deny no way in hell  if you want to shack up get your own place.
