pussy photos in his phone 😒

My ex and I has been on and off for about a year. When we break up it's only for a couple of days & even when so, we still spend time together until we fix the problem....so this time, we figured we'd make things work for good & we've been really good together, getting a place together and everything. So today I was taking pics on his phone and ran across a females pussy 🙄 (Disgusting looking) & it literally broke my heart. I knew we weren't together at that moment but we never break up for long... I guess it hurts because I never do anything like that. He said it was nothing and he thought we were really done this last time but even so, how can you just jump right into talking about sleeping in someone else's bed. He never physically cheated, but sexting and exchanging photos is cheating to us women!!! I really love him, I do & I know for a fact he loves me too. I just don't know😔. & the arguments been because of his lack of affection, so me seeing that pic makes me think that's why he's been lacking because he's been entertaining someone else. He swears it's nothing & the girl is from his hometown & he's really far from there but still 😔. I know he loves me but sometimes, is that really enough?
