A dad has been left feeling "unbelievably awkward" after discovering he has history with his son's new girlfriend. The 45-year-old man explained how he had a romantic relationship with his son's new girlfriend two years ago - but it ended due to distance.
However, she now has a one-year-old son - and he doesn't know whether he is the father or not. Taking to Reddit, the man claims to have made the realisation after his 28-year-old son proudly introduced him to his new girlfriend. He said: "There was no cheating involved whatsoever. I'd never do that to my own son.

"He's only been seeing her for about four months from what he's told me but she and I dated two years ago.
"It ended because I was going to be traveling out of work for months - we just lost contact.
"She has a one-and-a-half year-old son that is very likely my child. My son told me the father isn't involved but she hasn't given him any other details other than it's just her raising the kid.
"I was the one to connected the dots as soon as I realised it was her. You can't imagine how unbelievably awkward the first time meeting was.
After initially "freaking out" about the situation, the dad decided to come clean and tell his son everything.
"The conversation was not easy at all. My son was very confused and upset as would anyone honestly," he added.

"I expected him to yell at me but the shock was too much for him to get a strong reaction but he was still very serious.
"I made sure he knew I'd understand if this is too much for him so whatever he needs from me I will try to do. As of right now, he just needs some space."
The man urged his son to have the same conversation with his new girlfriend - but is unsure whether that happened.
He said: "He didn’t talk to me all day until he sent me a message earlier telling me he loves me but he's gonna need some time to himself which I completely understand.
"It's not going to be something he'll easily get over.
"As far as paternity, we still don't know anything about that. I have communicated with her about finding a place where we can get this test done and out of the way."
While most users shared their shock over his situation, others urged him to get a paternity test as soon as possible as his son might be unknowingly raising his own half brother.
One user said: "This is a terrible situation to be in and could've been prevented had she simply been honest and told you about the pregnancy.
"I think you're doing the right thing by everyone involved by bringing the truth to light."
Another user added: "Id never be able to cope with the fact that my girlfriend had been with my dad."
A third user said: "This is what a responsible parent does. I commend you for doing right by your son and possible other child.
"I really think you did the right thing and I hope that you guys can all find peace and connection out of this extraordinary situation."
