Does my colleague like me?

So there’s this girl at work that I’ve got to know over the last 6 months and have talked to sometimes at work and from the many times that I’ve talked to her I get the impression that she may like me but equally I’m not sure If I’m just reading into it too much. Overall she seems to really enjoy talking to me, seems upbeat and has no nerves or anything. There are some signs/behaviours that she’s displayed that seem suspicious to me so I just wanted to get others take on this. So this girl and I are in different teams and don’t work directly together so we don’t see each other everyday but have had some projects over the recent months where we worked together and overall we see each other on an occasional basis. In addition we live near each other so sometimes we run into each other after work on the way home and during lunch breaks too. Even before I properly met this girl I always had this feeling/impression that she had her eye on me. When we met the first time, after talking about our work related stuff we started talking about life, family, backgrounds etc and she just randomly dropped that because of her family and background that she’s currently under pressure to find a boyfriend or husband. I found that really odd that she told me that and that it was in an environment where it was only the two of us. Another time we were at a training together with plenty of other people. She sat near me and my team members and over the course of the training my team members and I cracked plenty of inside jokes especially me. This girl just laughed along even though she had no clue what I or my team members were talking about. This also raised suspicions for me. On another occasion which was just a few days ago, I playfully hit her with a chocolate bar and she blocked my arm with her arm. So our arms physically touched. This was the first time we touched each other apart from a few high fives over the past. I’m guessing she liked this or felt that since we touched now that she can touch me in the future or something idk. Because I ran into her the next day and just chatted briefly and when we were done she said see ya! And touched my arm which she’s never done before. Every other time I’ve spoken to her or ran into she’s just said see ya and moved on but the fact that she suddenly touched my arm raises suspicion and makes me wonder too. Like I feel like if she was just friendly or a touchy person she would have done that many times before too. So what do you all think? Is she showing signs that she likes me or am I just reading into this too much? Thanks
