In-Laws didnt want me know about my husband's suprise bday party

Me and my husband found out that his mother and sisters didnt want me to know about it. Theres a whole lot of insinuations n innuendo n its giving final boss level shade. I wrote about this at length in snother post. We been married for 8 yrs and I'm reaching the end of rope n considering divorce. I feel like thats exactly what they want. The question is: do I? I'm tired of the games. My husband is upset about the whole thing. Im upset that the foolishness keeps getting entertained by him. Wen some one show u who they are belive them. I hate to say its his immediate family or me. So I feel like I have to make a choice for myself: continue to be in this relationship or not. Im hurt and saddened that almost a decade in it has come to this. I dont know what to do.
