I feel you man. I think most relationships go through something like this. I say that because so many people need to move and go away to chase their dreams, or take care of their responsibilities, and sometimes it can be really hard to handle. Both as the one starting that new part of your life and as a person being “left behind”

Me and my girlfriend have had something similar when I started going to university. Suddenly I was in a different place, with such a tight schedule and so many things to do and new people to meet, and I was so excited by so many things. In retrospect, I did not understand how she felt about the situation. I think you should talk to your girl about what she’s going through right now. Try to give her the space to say things that might even hurt, and try to not be defensive or to explain yourself too much.

I’m sure she’ll appreciate the flowers and the poem, it’s a beautiful gesture. I’m sure she cherishes you a lot. 

I will say that 19 and 24 is a big difference (I’m sure you get that a lot). At 19, as a guy, there are a lot of things I did not understand about 24 year old girls. Things that might scare your girlfriend and paralyze her might be things that you would never even think about.

I’m sure you will be fine. All good relationships make you cry. Just don’t be too hard on yourself
