<human>: I'm dating a girl I've known for quite a long time, and we are almost a year into our relationship. She's great: kind, beautiful, intelligent, social - checked all the major boxes. We spend time with each other, our own friends separately, our friends together, and normally everything is fine.

One issue is that she is often on her phone (facebook, texts, news). Most of the time, OK. However, sometimes we have a conversation and she stops listening to me to do something on her phone. I give her the benefit of the doubt generally, but sometimes she has actually stopped paying attention to me, mid-conversation. I will stop talking in the middle of a point, and she does not notice or ask me to carry on, so I know she is not listening. This, is less OK to me. On the other hand, I listen to her and offer my thoughts with my full attention. I brought this to her attention; she noted it and had been better about it.

Recently, she left for the holidays (expected). She has been texting (sometimes calling) me, but I almost always initiate. I understand that she is with family, friends, etc., and I don't expect her to be at my beck and call. However, when I do try to talk to her, she usually responds initially a few times, and then stops mid-conversation. She doesn't tell me that she's busy, which would be fine - I'd let her be. Usually when this happens, I ask when a good time to talk is, to which I get vague or non-helpful responses. So I'm stuck with these intermittent half-conversations, not knowing when I should be trying to talk to her, or when I should be waiting to hear from her. She knows I do not like these half-ass conversations and genuinely want to have a full conversation. I have brought this to her attention again; she noted it and has said she will try to be better. So far, inconclusive results.

Am I being too "possessive" and worrying too much, or am I being (kind of?) reasonable?

Thanks for reading, this is also a chance for me to just vent.

Summarize the given text in a few sentences.
<bot>: Dating a girl with normally good communication, but she often stops paying attention or responding mid-conversation with me. Has increased since she left (for holidays). Thoughts?
