Hi guys I’m 21 and my ex coworker who is at least 5-10 years older than me keeps messaging me “hey”, and I’m not sure what to do? I feel rude for ignoring him but also uncomfortable from his constantly texting me hey? Am I wrong for thinking that he’s suspicious or weird for it? It’s like the 5th time. Should I block him? I feel bad because it seems like he may have a mental handicap and wants friends but at the same time he can talk to other men his age
