I was dating a guy on a regular basis and he initially told me that he had deleted his profile. You started off as a piece of ass, had some sort of conversation but really remained a piece of ass, now you're going to remove the initial attraction, sex, and you think, what, that things are going to change for the better? Guess you and him were just not meant to be, and you found out sooner rather than later.
Once they get some form of feedback that you are into them, this is when they can get shady. Only you will know if the answers he gives you can give you enough peace to continue seeing him. I had asked him previously when we talked about exclusivity and he said he would PROBABLY stop using the app and that he doesn't use the app frequently. They say things either in the moment or because they want you to like them. What does "I Love You" mean to you?
