You tell him your thoughts, and you need to be honest with him. Chasing can be good but it ends up frustrating. I used to do it all the same at college, women pretended they liked me, but when i went forward to them to hold their hand. They slapped my hand away and kept walking away, only to do it all over again. I didnt become insecure but it made it think i do not need to waste my time on these girls.
