I need to speak to someone about this issue, I wanted a male and females opinion. It's a long story so please bear with me.
So for the past 5 nearly 6 weeks I've been seeing a girl from work. We hit it off straight away, speaking nearly everyday, going out on lunchbreaks together most times. We've been for dinner together and a couple of nights out, she's stayed at mine and visa verca. Last Monday night we were chatting but she was been grumpy and just stopped chatting. The day after at work she hardly spoke 2 words to me whether if we saw eachother in the office or on messages. Later that night she apologised and said she has moments where she goes into her own little world and doesn't speak to anyone including family, personally I thought it seemed odd but I'm still getting to know her so I didn't really think I should judge. Day after she was back to normal again and we spoke as normal. This weekend she came to mine and went out, had a great time and she left Sunday evening and told me she had a lovely time. Once again everything seemed good. However yesterday she went into the quiet stage again, barely a word, she claimed she was busy with work but that's never really stopped her before and personally think anyone can find time to speak to someone, this continued after work. This morning she seemed to talk first thing but then has gone quiet, I've asked if there's anything up and she says she's fine so I have to take her word for it. I asked if she fancied going for dinner together but she says she's busy all week.
The point I'm getting is that I feel like recently she doesn't appear to be like she was before. We've both already stated that we want to take things easy because we both came out of long term relationships. She claims that I've made her happy again because she had a torrid relationship previously, so I'm thinking (wishful anyway) that I'm not a rebound. I don't want to be too pushy but I can't lie something just doesn't feel right, she said before that if she's not feeling it with someone then she tells them and won't waste eachothers time. As we aren't in a relationship I don't feel I can talk about this much because technically we are both single, however I've invested alot into this already, emotionally especially. She claims she really likes me and I've told her the same, but last week or so something doesn't feel right. I don't want to keep asking if she's OK because that will drive her away like anyone.
Am I overthinking too much here or would anyone say I have reason to be doubtful?
