I'm a compulsive liar to hide the fact I'm alone
What is your reason for lying?
I want other people to think that I am in a relationship.
It is awful that you cannot share what is really going on in your life but you shouldn't lie. Even if it is a good reason people will still be upset and feel betrayed.
Also, I don't want anyone asking me what is happening in my love life. I hope you understand that.
While it makes sense that you may be tired of telling people that you are not in a relationship, it is also wrong to lie to them. You may just want to talk to them and let them know that is it really annoying for you to constantly talk about your lack of a love life.
