I Cannot Tolerate Extreme Insecurity In a Romantic Partner

I have a business page for our farm and I put a picture of myself up to show people it's not a scam, there is a person available to speak with.
Well, I got a message from some older fellow who was hitting on me, telling me how beautiful I am and wanted to 'chat'. I immediately blocked him, didn't even answer.
My boyfriend and I have had issues in the past because he doesn't like other men complimenting me and when he finds out I talk with male friends (who I grew up with or from high school - not romantic exes) he accuses me of 'cheating on him'.
So, I was honest and told him about this message and his response? "I don't see why you put a pic of yourself on that site anyway. What do you expect?". I was livid! I told him I'm not responsible if people view my pic and hit on me ... putting my pic up isn't "asking for attention".
You know, I'm damned if I do and damned if I don't. If I don't tell him and he finds out I'm a cheater and if I am honest and tell him I'm asking for it! Seriously???? I guess this pic was "asking" for some creeper to harass me. FML
