Oh yes. If you have to stay in contact with them try to stay civil (I know that is very hard to do) and spend very little time interacting with them if possible. There are some that love drama and problems and they thrive off that. I find trying to be super nice to them doesn't work most of the time. Be super nice to those who deserve it and be cordial to those who are difficult. It just seems a lot of people nowadays are in angry/petty/jealous mode. I find these people are often jealous of what you have and/or envy you. If you can get them out of your life then do so. Don't let these people steal your happiness. Energy vampires. :(
Dealing with a similar situation just posted about it, my fiancé and my family can't get along but, I get along well with her family it's just hard for me to get mad with someone I can get an argument with you right now and be talking to you 30 minutes later like nothing happened just how I am lol.
Yes, I have had it too unfortunately. Some people I feel like I almost have an immediate reaction to. Not many but occasionally and I feel bad but I just am at odds with them. Husband has a friend like this. No matter how hard I have tried, I can't shake my feeling that I'm not a fan of the guy and pretty sure the feeling is mutual. Oh well.
