notice how the blame for this is piling onto you now OP... He's not good enough, he prioritises everyrhing else above you, but as you're still happy for any morsel, he'll keep you hanging around by saying that it's YOU that is suffering as a result of his depression.
Not his attending footy, oh no. That didn'y get pushed to one side, him passing up the chance of a weekend away with his supposed GF, on a rare away trip? A chance to make things up to YOU on your birthday. He could've chosen to make up for the depression by taking you away, making a fuss of you and he'd be bound to feel good. But instead he'll just pretend he never said anything about it.
This guy is a waste of your time. He's not taking you seriously because you're still technically living with your STBX.
You will miss the idea of a sucessful relationship, but you don't have one. That's not necessarily your fault, but as I've said on all your threads, stop looking for a crutch, get rid of this bloke, get rid of your Ex and see who you are. You won't be missing out on finding the love of your life, there are some transition men to learn from (labrats if you will) first.
Stop thinking that other people are your last chance of happiness, they are not. Only YOU can bring about that change. YOU get to choose the lucky man that will be your forever man. YOU!
Trust me. I'm preaching what I've practised.
