People are unbelievable !!!

I’ve been dating my boyfriend for about a year now and I hate that people are still trying to get in between us . Like today I was just here living my best life and my boyfriend sends me these text that someone sent him (unsaved number ) basically accusing me of cheating on him and saying that I shouldn’t trust me . The worst part is that my boyfriend got cheated on in his previous relationship so ofc he has trust issues and make the whole situation worse but honestly no excuse I promise him all the time even from the beginning that I would never cheat on him and it actually hurt my feeling that he would accuse me of doing that to him I love him with all my heart yet I never get the trust I deserve
