What do I have to do to make it simple?

This is quite a confusing problem you have. Firstly about the comments on the picture I’m sure that would have hurt to see but sometimes someone is friendly with people in a way thats misinterpreted in a way they really didn’t mean it to be. If he has waited for you for so long I’m sure he didn’t realize the way he was talking to the girl. Well you have to figure out whether you love him or not, you may just like himvery much so you cant get him out of your mind. If you love a guy normally you can’t imagine leaving him but this could change if you feel hurt by him so your feelings may have a normal explanation. You have to thnk about why you think about leaving him, if its because you feel you’d be fine without him he probably isn’t the love of your life, but if your reason is you cant get over the comment he made you are probably just feeling betrayed and should give him another chance. Nothing is wrong with you, even though he’s been great to you, you may not feel the way you really wish you did. However if its the comment that is really bothering you you do need to ask him ASAP so you can take that stress out of your life. When you two are alone there is no easy way to bring it up but you should just start with something simple like “Can I ask you something” or “There’s something I’ve been meaning to talk to you about and its been bothering me a bit which is why I’ve been quiet lately” (if he doesnt know the problem he may be nervous about what’s going on with you so its good to give him an explanation, not speaking your mind will do more harm than good) Lastly I’ll just speak from personal experience I have been out with a number of guys but I could see myself doing fine wihtout them and my mind strayed frequently to thoughts of how we would break up. Since I had felt like that with every guy I thought it was normal, However I know I love my current boyfriend and I cannot imagine us splitting up it kills to think about. So it would be a good idea to really search inside yourself to find the root of why you think of breaking up with him Hope this helps a bit and doesn’t confuse you too much. Good luck I hope all goes well! x
