This is a grave error. When a man tells you he does not desire a relationship, you must accept his words and move on.
Anybody is interested in dating you will ask you out. If he does not, something is holding him back, so proceed.
If he is above 40 and has never been in love, he does not want to be in love. Don't be fooled; simply walk away.
No matter how entertaining messaging him is or how "into you" he looks, do not waste your time. If he was sincere, he would meet you in person.
Bad mistake! When a man says he is not serious, he is not joking. Drink your wine and then say farewell.
He visits your home, but never takes you out for a formal dinner date. Why? He probably cannot risk being seen with another lady in public.
Do not act as a placeholder if you wish to avoid feeling silly. Drop him immediately if he does not ask you out, regardless of the reason.
