I Am In Love

I'm madly in love with my girlfriend but she's pulling away alot recently and I don't feel her love for me anymore. It's a terrible feeling. Knowing it's partly because of my mental illness and my insecurities that spawned because of my childhood. I want to show her how much I care and love her but she doesn't seem interested. I feel like giving up but I can't find it in my heart to do that. I just want to make her happy and spend the rest of my life with her. Holding hands as we are old and grey sitting on the rocking chair together watching the sun set.
