So many red flags... He made himself available too soon; he shared way too much too soon... do not meet him.
I don’t think he is posing as a gay man nor he has any plans to attack or hurt you. I think this rat smells a bit different. Something isn’t right and I don’t know what it is but I also wouldn’t recommend that you take the risk to find out.
Although you seem to be open to having a date with him, so....in that case here is an idea: can you make sure that at least two of your trusted friends know about the date/time of this date? If something happens and if they don’t hear from you at a time that was previously agreed upon they can call or take action?
