I'm not too sure if this girl likes me or not and I dont know what to do?

I speak to this girl like every day on Snapchat but we spoke a lot in real life but not any more because she moved away to Spain. She will come back so thank god. I spoke to her during my free time during school and everything.

Thing is I'm a bit chubby maybe a little bit fat but I am slowly losing the weight but personally I'm not a hot guy an all. We laugh a lot and we always speak about how we hate school and look forward to move away to go to University. She has told me secrets and I have told her my deepest secrets who I never tell anyone.

She is also going to Formal this year but she's taking her sister as a friend but I would feel awkward to ask as I dont need to ask because it's her Formal aswell as mine. she's really nice and sweet and we always reflect and look forward to once we finished School.

Also we share movies in common and I just feel awkward as she lives in Spain. I really like her but I'm not too sure if she likes me, but like I said I am a bit chubby and I'm not too sure if she likes me the same way. We are best friends and I even have the snapchat yellow heart ahah.

Any suggestions or advice?
