is it me orrrrr??

so married my husband and thought everything was good but i am so stressed out lately! after our miscarriage i kindof went off of the radar for a bit bc seeing babies and happy things were just too much. during that time it got to me more how my husbands family is absolutely horrible. they take bets on how long we will last. his mother says horrible things about me like either im too confident or not confident enough. im not good for him. she still takes his ex girlfriend out to things and became best friends with his exes mother talking to her about how horrible i am to the point of her messaging my husband saying horrible things about me. his father tells him he needs to reconnect with exes and he shouldve never married me (my husband notices after the say things about him but for some reason doesnt see how his father saying those things were wrong. his mother and him shared a bank account which i had no access to and she flipped saying im controlling by wanting him to close it and have a bank account with me. his younger brother even tells him hes gonna beat him up and how he shouldve married him instead bc at least this wouldnt happen. my husband cheated on me bc it was my fault i want enough for him-his mother said that ugh and more. our neighbors smoke right on the front which is against the rules and they throw their cigarette butts all over the yard to boot shes pregnant drinking and smoking so were never really good friends. but i told her husband to please pick it up bc the garbage and butts are spilling into our yard. and then my husband told her.....which turned into a doorbell ring late at night to her husband telling me off threatening me and being aggressive and her saying i forced my husband to say that to her bc i have a problem with her. her husband told my husband to "check your wife" like he couldnt of done that byhimself it was my fault. ive been focusing on myself working out volunteering focusing on myself and my family and yet it seems like everything that happens turns into my fault? is it me? i keep thinking im the only same piece in all of these problems. is it me?
