<human>: Throwaway for obvious reasons.....

Heres the situation,my SO is still in school and she works very hard and i work so the time we spend together isnt alot. I do walk her home each day or eat out with her but its rare we have romantic date nights or just nights where we just relax since i have work and she has school.

We had a romantic night planned on friday but she suddenly cancelled since she said she wanted to study. Which is fine because i want her to do well in school. Then on train yesterday she gets message from her friend to hang out and texts back quickly since i was next to her. 

I ask her what it was,and she was planning to go out and have a couple drinks with her friend. That made me mad and i kinda did tell her but she said she needs space,she sees me everyday,and wants to see her friend.

Personally this bothered me because yes,i see her each day but i walk her home,i want to have date night or drinks with her since we barely do that because our schedules. She also texted me that she should have thought how i would feel after finding out her plans.

That rose a red flag because how the heck does ur SO not prioritize or think about your feelings first before others.

Am i in the wrong for being annoyed???? What should i do??? 

sorry for bad english as well

Can you condense the text into a few key points?
<bot>: SO cancelled plans and secretly had other plans with friends. I am annoyed because we barely spend quality time together. Is this normal?
