I share your frustration. I have been playing for four years now. I am 60 years old. I want to get better and I am improving, but it is a painstakingly slow process - Worse than watching grass grow! I also cannot listen to a song and play it without looking up the chords to the song. But my ability to to start playing new songs has become easier. That much I have noticed. An hour a day is a lot. I sometimes play for only a few minutes a day, and sometimes I can go for a couple of hours. Like you, family time gets in the way of my progress, and I feel guilty picking up and playing the guitar when I feel like I am neglecting my family time, so I will put down the guitar. I really wish I had started playing when I was much younger. I am sure that I would have progressed much more quickly. Best advice I have is to practice the hard parts to songs. The easy parts will always be easy.
