The finding fun/ get a life tactic is NOT designed for you to behave like a trained seal, checking his reaction at your every move.
The get a life tactic is for YOU to find something to do to make you feel better so you don't concentrate on him. If your GAL tactics are all done motivated to get his interest you aren't getting a life. You are essentially walking forward while looking behind you - it doesn't work very well.
GAL means to do something fun for yourself and NOT tell him, and NOT hope he pays attention, and NOT pursue him. If you call him to tell him you are getting a life you are pursuing him and using the GAL activities as ammunition. My dear, that does not work.
You CAN leave subtle hints around, but it means you must LEAVE him ALONE. If you are swimming, leave the swimming pool schedule on a desk someplace or leave your swim bag by the door. Or even better have some friends come by the house to pick you up and go as a group. But it means you do NOT APPROACH HIM DIRECTLY on what you are doing.
You called him up, told him outright you were doing things, and then criticized him for not noticing - this is PURSUIT. You are not supposed to be doing these activities like a dog rolls around for biscuits. You lose your dignity when you do that, and its not sexy or inviting - its annoying my dear.
The objective is to do these things and leave HIM to THINK, give HIM some space to BREATHE. You are doing activities my dear, but you are sabotaging any positive impact they may have when you call him up to report on them directly.
If you can list what you are doing specifically we can help you with some ideas on how to leave hints for him to see what you are doing. But they have to be hints, expose him in a very subtle way that the OLD YOU is GONE and the NEW YOU is HERE. But it has to be subtle and non-invasive. You have to bait him a bit here and wait for him to bite. You calling him effectively means you are diving in the water to chase after the fish. You will just scare him away.
My advice is for you to skip a call now and then. He said to call twice - FORGET TO CALL.
Leave him some space to breathe, to realize HE is not the linchpin of your existence. When you call him you put a lot of pressure on him to be the exclusive motivator of your life and he can't take that. He needs to feel like you are surviving on your own. He needs to feel like he can breathe around you. HE is walking on eggshells around YOU. That's why he doesn't want to be around.
You need to be casual about him, let him know he can be part of your life, but that if he makes a mistake, if he is late, or has something to do outside of your life that you won't turn into a hornets nest of need. Calling him up to report what you have been doing and criticizing him for not noticing is NOT casual, its NEEDY. No one likes a big ball of need calling them twice a day.
Sorry to bullet my point home here but this has been said already and it doesn't seem to be sinking in. He DOES love you, but you need to leave him alone and give him a REASON to seek you out. You are just giving him reasons to avoid you.
Your phone conversations are the same thing. You are stressing him out. He sits there trying to figure out what to say to you and you are there like some drama queen waiting to react. He can SENSE that. You are putting way too much pressure on him. When you pressure people they RUN AWAY. Unfortunately they end up looking for company when they get to a safe place which ends up making matters worse.
Call him and act like his call isnt' that important, or better yet wait for him to call. Have some friends over and only pay half attention to the call. Leave him feeling like he HAS to CHASE you a bit to get to you again.
There are ways to bring this guy around, but hanging on his ankles over every phone call is NOT inviting or attractive.
What I would like to see you do is make a list here of all the activities you are doing outside of your H and talk about THOSE a bit. I for one am interested in hearing what you are doing.
