I think he needs a come to G meeting! The Dr. and I usually text a bit in the morning, usually a brief chat around lunch then we chat a bit or talk on the phone at night. I don't know what kind of job he has but everyone has time for something brief. This morning I was at the gym and sent the Dr. something simple..."Good morning beautiful, have a great day! Hope you slept well". It doesn't have to be much.
Just remember a couple of things. If he wanted to break up he already would have done so, I do believe he loves you. I think it is going to come down to whether or not he can give you what you need. If he is willing to change and be more present, be more aware and understanding of your needs. Does he have the ability to do so or is this how he is hard wired.
It doesn't mean he is a bad person as the way he is could work for someone else. Ultimately if he can't change it just might not work for you.
As a suggestion I would make it crystal clear to him what you need. In my marriage my XW didn't do that and unfortunately I was not equipped to read between the lines. I heard the complaints but didn't understand the seriousness of them. If you love him do him and yourself a favor and make it crystal clear so there is no mistake in the message you deliver.
