Am I overreacting?

Sorry but holding hands, letting her flirt, calling him all the time, etc… .. you think that should be an ego boost for the other girl??? On the contrary it ought to be a huge red sign for her to have a serious talk.

If you’re a good looking chap with a decent personality, lots of girls show interest in you and if you’re committed you need to take caution. I dont think doing this is a little too much; anything for the person you love right?
