12. He accidentally touches you
I think it’s obvious that when a guy touches you, it is a sign that he is flirting with you. However, when he accidentally touches you, this is completely another sign. This means that he’s trying to get your attention, and he’s trying to find any excuse to start a conversation with you.
If you are interested in him, feel free to do it back! Unfortunately, many of us ignore this sign, but who knows, maybe he is your future husband?!
