A lonely mama in need of your wise words.

I have a meddling sister in law who seems to cause a lot of tension and problems between my husband and I. I decided removing her off all my social media will help prevent any future drama and I was wrong. It just made more since she got offended. Her actions are making me resent my husband and act very rudely towards him. Hes mentioned he doesnt want to get involved etc etc. Whats truly upsetting me is not her, i think now I know ignoring her is the way to go. But what's upsetting me is how poorly Im treating my husband due to this all. We are ttc. We took a 3 day getaway and fought so much and she was the center of all our fights. He went to work this morning also upset. We never fight!
