Texting is NOT ok. It is cowardly. Claiming to have feelings for someone and then dismissing them in virtual reality is pretty low, morally speaking. If you can't face someone else's emotions, you have no business being in a relationship.
If the poster is going to see him on the weekend, THAT is when he can do it. Face to face. This is why people are so cynical about what they call 'Love.' They pick the wrong partner for the wrong reason and when it is time to do the right thing, which is the respectful thing, they opt out. That is not the behavior of an adult: this is the behavior teenagers exhibit around the age of 16. If one is doing this at 30, one can reasonably assume one is more likely functioning in the same way as a16-year old, emotionally speaking.
Even though it will be uncomfortable, prepare him by telling him that there is something important you want to discuss when you arrive. If he chooses not to ask a followup question, the odds are good that he knows what is coming and is avoiding it. That's no excuse for your behavior, though, should you choose to pretend all is well. One can be an adult or one can avoid growing up. Breaking up is no fun for anyone, but your past behavior - how you handled your last anything - is an indicator of what you will do the next time. This explains why guys (and women) continue to pick the wrong person. It's not the other person with the problem: it's us. One cannot eternally blame the other person. A therapist once told me, "The worst thing you can do when you are dating someone is to stop assessing in the early months." There are almost always signs that warn us, but we ignore them. He's ignoring signs. The question now is: are you going to participate in the "elephant in the middle of the room that no one is discussing" or are you going to say what needs to be said?
