Sister in law and brother in law

Would love coaching on my relationship with my sister in law and brother in law. I love them both but because of hurt feelings on their side and my husband and I and them taking different sides in my husband and his brothers parents divorce, (we sided with his mom and they sided with his dad) we haven’t seen each other in over a year though we live mintues away. My husband wants nothing to do with them, despises his brother and thinks his sister in law is crazy. I can see where he’s coming from because of how he’s been hurt by some of their actions (or I should say his thoughts about their actions) but I really want to have a relationship with them. I feel I’m okay with the crazy and can handle it. I don’t get offended easily and things they do that offend the rest of their family and have caused them to not be speaking with anyone in the Family downs brother me. I would like to try to go visit and try to see if I can get the Sister in law to meet and even let her tell me her side if she wants. I’m all in and only feel love toward her and her family. The only issue I’m having is that this is really my husbands family, and if I let these people into my life that includes my children and ultimately him. And I know that where he’s at with his thinking he will not want to have them in his life. I don’t know if I need to just keep loving her but understand that I won’t be able to see or talk to her because I want to respect my husband and his feelings or if I try to reach out and just have a relationship with her and her kids the best I can without involving my husband. Hope this makes sense. I know you never give advice on what to do- you’ll say I don’t know what you should do. But I’m having trouble maybe seeing it in the right light. I know you also say what would love do? I feel like I’m bursting for love for this family and just what to send gifts and give hugs and play with my nieces and nephews and take the good in with the bad. But I’m a devoted loving wife and want to stand by my husband and respect his boundary of not communicating with his brother and family due to past experience. Thank you for any insights! Love you and this work!
