One of my girlfriends friends had a situation here she thought he was cheating. I was the only person that said he could have been busy and it ended up he was whn everyone else thought he could be. However I am not saying he isnt doing these things, but if yo honestly believe he loves you then you could contront him. Honest love should have no problem saying things to each other no matter what it is. Though I do remember one time I thought my girlfrind wa cheating on me. I just never really trusted her at this point cause she didnt fully trust me. Though after I found out she actually wasnt when I thought she might and figured things out I felt horrible. Just becareful what you do. Its no wrong to find out, but just be careful cause if he isnt or even if he is you can feel bad for doubting him. Though if I were you I would just ask directly, that is just me,talk to him easy about it, well that is the honorable way to. You could just ask his friends and or follow hm, hidden camra’s do good.
