If you have been seeing each other for a couple of years, he has had ample time to know whether he wants to be exclusive with you.The fact that he has not decided to be exclusive with you, and prefers to see other people after all of this time, is evidence that he is not sure you are the right fit for him.The last time I saw him, I asked him if we could define our relationship. I decided that everything was probably okay until yesterday when my brother went to a coffee shop and saw him with another girl.
If by then he still hesitates at being exclusive, it is time to let him go.
At a minimum, it is a waste of your time, as more likely than not, non-exclusive relationships peter out. It is rude and disrespectful to be subject to such behavior. Dating someone while they’re dating other people is the same thing.
At worst, you are setting yourself up for heartbreak, getting attached to a person who refuses to focus on you. While he’s out with you having coffee, his mind could be on the dinner he had with her last night. I know many people think, It’s okay if he’s dating others besides me.
Even friends and family have tried to convince him that I’m “the one”.
Yet, when we are not together, it’s like he can care less. I would do anything and everything for him and he knows it.
