Bio-Mom thinks she is our niece's aunt also
I'm new to this, so bear with me. My husband and I have many problems with his ex-girlfriend (not ex-wife) they were never married. She still remains good friends with my husband's sister and actually moved the stepchildren 100 miles to live two blocks from his sister. You can just imagine the legal fight (and family feud) that entailed, but of course, she won because she had a great job lined up for her. Well she quit (or got fired...who knows) 10 months later and as far as we know now, she works part-time when needed. We have many, many problems with her, especially her need to control everything. My husband is a wonderful father, supports the kids anyway they need it. We have them every other weekend during the school year and all summer with bio-mom receiving every other weekend. The oldest played baseball (which started during the school year) so my husband even went as far as picking him up 100 miles away so he could participate in practices and return him home the same night for school the next morning.) Driving is 50/50 during the school year and 100% her responsibility during the summer. She had the nerve to throw a stink about that when she was the one who moved them so far away. My husband has gone to band concerts, teacher conferences and many more events, having to drive 4 hours total each time. Very devoted father. She takes advantage of many situations with his family. Like I said earlier, my sister-in-law lives 2 blocks away from them so when her daughter (my niece) comes to visit Grandma (who lives right down the road from us), Bio-mom likes to use that to her advantage to have Grandma bring all the kids back. Let's just say she gets out of her driving time a lot! Okay, I'm going off track, sorry.
The reason I wrote this forum is because a new problem has arose (at least in my eyes) and I just want some advice. Bio-mom has been referring to herself the last couple weeks (in the public eye) as our niece's aunt. Our niece is my husband's sister's daughter. I get that sister-in-law and bio-mom are good friends, sister-in-law is not very fond of my husband (her brother), probably not fond of me either. Anybody can be referred to as an aunt whether they truly are or aren't. But I know she is doing this just to spite my husband and me. Do I confront her?
