Finishing Degree

So this is where I'm coming from, I have an amazing gf and this is someone I want to marry in the future. I'm 22 and have 2 years under my belt for school. I have the option to get an associates degree in exercise science or go for the longer and more time consuming BS degree. Which would put a strain on our finances and relationship due to not seeing each other and stuff. Might sound silly but I need some outer advice from people. Finishing the bs degree means I need to go full time, have my parents help with rent and expenses and a new car the list goes on and on guys. If I get the associates degree it would take much much less time and money and I could go back for my BS later. Idk any advice is greatly appreciated.
