I feel like I've missed out on so much

Emily

Me and my boyfriend have a twenty year age gap. I love him a lot and for me, although he isn't my first relationship, he is my first for a lot of emotions and I've enjoyed discovering things about myself with him. We live together and I do believe he loves me, but I feel like he often believes me to be immature. His friends talk about the good old days when he did this and that and ultimately I feel like I've missed out on his prime days. I wish I could go back 20 years at the age I am now to meet him. I guess I am jealous of the people around him during what he calls his glory days. Anyone else had something similar? How am I supposed to deal with these feelings I know deep down are ridiculous :(
