Need some fast advice please

So my boyfriend just went out to the bar and we both play games on the computer so I got on and I opened safari so I could search something for work and omegle had popped up because he had recently favorited it. And so I check the history and he's been on omegle in the last month and I'm not sure how to react. I'm trying to control my emotions so I don't overreact but it really hurts my feelings and I don't know if I'm more sad or angry. It's a known fact that guys go on there looking for girls who will strip for them and what not. So I'm having a hard time not finding this as a way he's been unfaithful. I get porn that's not an issue but this is an actual person you're talking and communicating with and that hurts. Please advice.
