DG its hard turning things around and you do have to let go of your H for it to work.. Ok you can keep ignoring texts and things to get him to call, but all that does is lift your expectations and then you feel hurt again.. You need to start being a little more independant.
In my own situation my little cat was the love of my H's life, and he started to come and visit after she had a bit of a nasty accident, but in your case he drops the dog off for visit's. By all means have the dog to visit but make sure its on your terms and is picked up and dropped off when he agrees to, atm it does seem that he is using you to dogsit not letting you have time with the dog..
The most important thing is that you need to become attractive and elusive again, atm you are at his beck and call, you need to turn that round the other way!
