<human>: Can you provide a brief rundown of the text in within 3 sentences?

My GF and I have been dating about 3 months but have known each other for a close to 2 years with some history in between that time where other factors just didn't let us happen.

Anyways!

She recently went away for about 8 weeks and we are currently 3 weeks in to her holiday.
Before she went away she told me she loved me, after I had already told her a week prior.
She has some walls up but has told me those have all basically come down because of me and how much she trusts and loves me, but there are still some left.

While she's been away we've chatted a bit, just trying to stay in contact and make sure she is ok and having fun and the same for me.
However, every time I've told her something good or bad that's gone on while she's been away she's seemed kind of dismissive and not very excited for me. I am not sure if I am just reading to much into things and over thinking but I've tried to get excited about what she's been doing while she's been away.
This is how I know she hasn't been really "excited" for me because her reaction to my news is way more tame compared to what she has been doing.
In terms of losing interest, she seems to fluctuate a lot with her affection and conversation about me at times.

I just feel like whenever I bring something up she either doesn't want to deal with it, doesn't care or simply is ignoring it and I really don't know why. For someone who claims to love me it seems like she's just being really distant with this and is only really interested in herself.

I'm afraid to bring this subject up while she's away because I don't want to start a fight or anything and I don't know if I'm just overreacting about the situation.

Specific examples can be provided if needed.
<bot>: GF is away for close to 2 months. Seems to be losing interest and slightly uninvested in my life and what's going on while I'm at home.
