Is it normal to lie to my friends

You should keep lying but make the lies more absurd and nonbelievable.
I have a few friends who are pathological liars who make up the most unbelievable bullshit and they are hilarious to hangout with.

I'm an older man maybe I can make your story become a true one lol

It's normal to lie, but lying for a long time about something major like that is pretty crummy. You've got two options here:

1) Come clean. Some of your friends may leave you, others may laugh it off, others will need time.
2) Cover it up. Just say screw it, and get to work on remembering it differently. Eventually, you won't even be sure it's a lie, and all will be well.

I suggest #2. Coming clean is dramatic in the movies, in real life it just blows.

No, this is not normal, but things can get better. Everyone lies and no exception but some lies are bigger and dangerous than some others. Saying " yeah I'm seeing my family today so I can't go shopping with you " to one friend because you are not in a mood for going out is not the same thing as lying about an abusive relationship that doesn't even exist. The best thing to do is also the hardest. You have to explain everything to them and apologize. But more important. Why did you need to lie about those kind of things ?

Who doesn't?

If you say something, you need to make really clear that you regret it and you feel guilty and that you're very sorry. Also explain how you felt left out and that you let peer pressure to have a boyfriend get the better of you. I hope they forgive you, but don't expect them to straight away. If someone confessed something like this to me, I think I'd need a bit of time to let it sink in before I could forgive them. Hopefully they will understand that you were feeling very insecure. It doesn't sound like you did it for attention, but out of insecurity. Just make sure you are totally clear about the fact that you realise it was a stupid thing to do.

No, that is bad what you did. You should come clean and accept the repercussions.

Lying is one of those vicious circles. Not only does it keep building, it becomes impossible to remember all the lies so your stories become inconsistent.
I think the greater question is why you feel the need to "fit in" or seek their approval. We are all individuals and it is that individuality that makes us interesting to others. We should all move at our own pace, not allow others to dictate our progress.
Obviously, you will get a BF one day, when it's right for you.
If these friends won't accept you as you are, then they are not frien0ds at all, just acquaintance and you shouldn't give a damn what they think.

Sorry, but this isn't normal. Well, I can only speak for me but....with my best friends, I don't ever lie. They accept me for who I am....or they aren't my friend! They often wonder why I'm still single, but I'll never make up a SO to "fit in" or embellish a story for the attention. I'm sorry you are in this predicament now....but I suppose you must now lie in the bed you have made.

Maybe you should tell a friend who you feel really close to. Someone you can trust that can keep a secret.
