So this is my first time posting a new topic on here, so please be kind! There's a ton of backstory and family history to all this, but I'll try to lay it out clearly, because I need some advice.
On Saturday evening, I was out of town on a week-long work trip (having left my 11 month old for the first time, so it was a stressful trip), and received a series of messages over facebook from my brother in law (DH's brother). He told me that he'd tried to contact me several times over the last few years, and I hadn't bothered to respond to him (his contacts would typically be Facebook messaging me a cartoon picture, or just a "hello", never an actual message or email- this would happen once every two or three months. We would chat maybe once every few months if I was at the computer when he messaged me), and he was thinking about cutting off our relationship. He described me varyingly as cold, arrogant, ignorant, condescending, standoffish. I responded by saying I couldn't discuss this over Facebook messaging, and that DH and I would call him to talk when I returned from my trip. He responded with more choice words, and added that he'd talked to his sister, and she agreed with him, PLUS they would prefer that I not tell DH about what BIL had said. Of course I talked to DH at length about this on Sunday and he said he would call his brother and mom to see if he could figure out WTF was going on.
I got back from my trip tonight and had a long talk with DH about this, and he said he talked to his mom yesterday. Her response was that she'd read the messages from BIL and she agreed with him- apparently the three of them have discussed this in person. She gave no details except to say she'd tried to reach out to me in the past to build a relationship as well, and that I wasn't receptive.
Long story short--I get along with MIL fine, but it's not a warm and close relationship. I really liked BIL and SIL and thought we had a really good relationship. I text MIL and SIL baby pictures several times a month and talk to them occasionally when DH does (he talks to his mom probably 2x a week, sister maybe 1-2x a month). MIL was just out here last month staying with us to visit the baby- she also came out when the baby was about 6 weeks old. We go to their house for Thanksgiving (in the mid-west, we're in DC) and typically once during the summer. We only see BIL and SIL when we go to their city. SIL and I went out over Thanksgiving for dinner and drinks and I thought we had a great time. She had asked me a few months ago if she could use my family's beach house for a weekend this summer- I said of course- and we were going to ask her (this week, actually) if her daughter (our niece, 10 years old, who's amazing and I adore) could come stay with us for a week in August.
DH is super supportive and awesome, totally on my team. He told his brother he couldn't talk to him right now about this, but his sister texted him and repeated the same words BIL used to describe me- arrogant and condescending.
I don't know what to do. I felt like we had a comfortable relationship where we were in contact several times a month. This is honestly more than I talk to a lot of my friends who live out of town, and DH and I have only been married a couple of years--so I don't know my in-laws all that well. This past year has been super busy with a new house, new baby, new job, etc, and I honestly have felt pretty tapped out, then all this drama happened. I knew that my in-laws wanted more of a relationship with me (more frequent, with me calling them to talk on the phone), but I have been trying to set boundaries of what I feel comfortable doing, and what I feel like I have the time and energy for. Thus, the texting of pictures and info, sharing photos with them on Facebook, face timing with the baby, etc. I think MIL and SIL expected all of us to suddenly to be tight girlfriends after DH and I got married, but that just hasn't happened.
DH and I agreed that he would handle this by talking with them, but I'm not sure what to do on my end. DH insisted that I block BIL on Facebook- he doesn't want me to get any more emails like the series of 6 or so that I got over the weekend. I did it, but I think that BIL will see that as the nuclear option and go ballistic. MIL, BIL, and SIL have all insisted separately that they're just trying to improve their relationship with me, but from my end, I feel like (a) it wasn't broken and (b) they just threw a pipe bomb into it.
Advice? How do I get past this? I want DH to have a great relationship with them, and for my daughter to know her family well, but this whole situation has set me back on my heels a bit.
