<human>: My girlfriend and I have been going out for only a short time (3 months) and I have gone overseas for a month. Before I left we were getting along really well and we loved each other. At the start of my holiday we were talking frequently saying how much we missed each other etc. A week after that she stopped talking to me and after another week she sends me a message:

*"...ever since you left my mind has just been plagued with these recurring thoughts about you and now my feelings are confusing me. I intended to talk to you about this sooner but I didn't want to hurt you and I didn't know how to say it... Before you get mad or freak out, please try to be understanding, this is hard for me also. I've been doubting myself and you and myself with you. I don't know whether I'm unsure only because of your absence, I think I'd have to see you in person again to reaffirm my feelings, but I just think you need to know the reason why I've kind of been avoiding you. I just really need time and space. I'm sorry, I never thought I would do this to you."*

I still really like this girl and I miss her everyday. Ever since she stopped talking to me I started to get really depressed and worried about her. What should I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Been going out with a girl for only 3 months and she stopped talking to me and is ignoring when I went on a holiday for no reason even though everything was going fine before. Help?
