venting/advice

So little back story, my husband and I have been together for 5 years, his brother(will call him James) has been a pain to me and I have always been nice, anyways James was dating my best friend, they were together for 2 almost 3 years, well James was at a party with out my friends and this girl(16 year old) come, and anyways James cheated on my friend with this girl. My friend and him broke up and he started dating the girl(Jane). They got a house Together and got married. Jane doesn't like me because I still hang out with my friend, and never choose Jane over her. Jane says I disrespected her because of this, does childish things like post shit about me. I have her blocked. Well it got worse when my husband and I got married. She disowned us(but I didn't consider her family). Now fast forward to last night, James need help and asked my husband if we can come help, Jane was at work. Well she found out I was there and posted I should never been there, I wasn't invited etc. anyways, James never comes over here because I think he feels as I hate him because of her. I was gonna text him, and tell him he is more than welcomed here and his brother misses hangout with him. But I'm not sure if I should. He has said some hurtful things to me and I feel like I shouldn't have to say sorry and everything for not doing anything but ignoring the drama. But my husband and i are ttc, and I do want my kids uncle in their life. What would you do?
Btw she now 18 almost 19, I thought the drama would be done by now. She was almost 17 when they fooled around. It's been almost two years. No one in the family likes her, we all try to be civil but she makes drama, and causes problems with everyone. She been childish since we met her. She always thought it's because she wears black or because she's not my best friend(that she needs to act like my friend)not not her personality or the way she acts to people. I mean she told me to go kill myself, but of course I'm the bigger person and said you shouldn't tel people that and took it as a grain of salt.  James is 26 years old, and was basically forced into marriage or her and her parents would go say rape like she did to someone else's. She evil and I wish one day she out of the family
