So our relationship with my sister in law hasn’t always been that great. We only hang out during family gatherings but our kids always spend the night at each other’s house. So last night I had her kids over because me and my husband get along with them great. Ages are 16, 17 and 10. So tonight my kids wanted to spend the night at her house and she said no, because her husband is stressed out since he has a court hearing with his son they’ve had issues with. He cheated on my sister in law years ago and now dealing with it. So, I just feel so pissed off that their kids were here last night but now he’s in a bitchy mood, can’t handle stress so doesn’t really want my kids over? Do I have reason to be upset or am I over reacting? At first she told my kids yes, then she called and said no. I just think that’s BS. Please let me know....
