My [22m] GF[21f] of 7 months is still unsure is she really wants to be with me.

So we've been together for about 7-8 months and things have had their ups and downs. After about 1.5 months of us first being together, she said she was overwhelmed with all her new responsibilities and life in general (just moved to a new city for school). I understood but really didn't want to let her go, but she said she wanted a break. She said when she first moved here she just wanted to meet new people but was surprised shed liked me so much, so we decided to go for a relationship after thinking about it.

Fast forward about 7 months, we spend a good amount of time together and when things are good, they're fantastic. I definitely do not want to be with anyone else but I have these feelings that she does not feel as sure. So after another fight one day (feels we argue about something about every other week), she tells me she needs a break, and I feel as this is the best thing as well. She also confides that she still has doubts if she wants to be in a relationship, but that she does love me. So we decide to take a week long break.

Two days later she calls and says she wants to meet so we can get back together. Well one of my friend's friend is like her guy friend and I found out she told him that she doesn't know if she loves me. Also that she's been talking to this other guy she met. Well we meet and I tell her i'm not so sure and I still need more time. She was pretty hurt.

Now I don't understand, am I just her safety net for right now? Did she really realize she wants to be with me after only two days, when she has had these thoughts for a few months?? Any woman on here help me out with the way you guys think please?

TL;DR GF has been unsure if she wants to be with me, I believe I just might be her safety net. Or is she just really looking to meet new people and actually loves me?
