Should you trust the people who chase you?

There this one guy that has liked me for awhile now and has always tried to settle down with me. However I’m scared that once I lay it out his chase will be done and he’ll leave, looking for the next chase. I’m in constant wonder of what keeps them in the chase in the first place and kind of believe people who chase just want what they can’t have. But i’m not sure. What do you all think?
