I’m pissed

My boyfriend called me today while I was at work and he said that a girl added him on snap and he added her back. She told him they matched on tinder but he says he hasn’t been on tinder and that his account was banned months before meeting me. He then proceeded to tell me he thought she was trying to fw him. So I asked him “why don’t you block her?” And he goes “I’m intrigued, want to know how she got my snap”. Then never talked about it for the rest of the day. So I asked him “did you find out how that girl added you?” And he goes “ yeah she found me on quick add and wanted to promote her only fans” I said “ did you block her?” And he goes “yeah because she sent me a half nude photo”! I have every right to be upset right? Or do you think I’m being over dramatic?
