<human>: Could you distill the essence of the text into 1-3 sentences?

My girlfriend and I both attend college, and we're on our Christmas break. All but two of her friends from high school have gone to different schools, and she says she has trouble making new friends in college. She still does have people to hang out with though. 

Over the break, she's been hanging with her friends and blowing me off quite often. Today, she texted me asking what I was doing. She went on to say she was bored. I said let's hang out. She said she wanted something to do, not to just sit around. I suggested the park, she said it was too wet, then told me she was going to hang with her friend and 'maybe' we'd meet later. She ended up bailing on me. We've hung out and had good times this break, but sometimes I feel ignored. I feel like I'm a backup.

I understand that she misses her friends and she wants to take advantage of the break to see them, but she hangs out with them almost every day and doesn't seem to want to make time for me. I feel like she only hangs out with me if her friends are unavailable. And when we do hang out, it's often with her family. We have had little alone time. 

Some supporting information: at school, we hang out almost every day. We've both told each other 'I love you.' The relationship was great ever since this break started. This break is a month long and I'd say 70 percent of it has been spent with her friends; which is why I feel like she could make a little bit of time for me. When I tell her how I feel she says she knows she has the whole school year to spend time with me and that she does miss hanging out with me, but it never seems genuine.
<bot>: My girlfriend blows me off for her friends, doesn't invite me along, and I'm starting to feel ignored and like a backup option. Do I have the right to feel mad or hurt about this?
