What do I do?

Assalamualaikum, a few months ago I had a twitter account. Long story shot I met a girl We talked quite a bit and I fell for her. We talked for about 2 months and she brought up marriage and I agreed to marry her (I know I'm st**id). She never gave me her number and won't Skype with me. Her story was odd and had holes. Two months after we met I decided it would be for the best if we stop talking to keep things halal. So after a month of no talking. The holes in her story were bothering me so I searched her name up on her university directory and she is not there. I start to talk to her again and this time i'm trying to figure out what was going on. I get one of her pictures and I do a reverse google image search and find out that the picture wasn't her. I also set up a honeypot trap and found out the IP address is coming from Missouri while she claimed to be from Boston. I confront her about this and they tell "I'm sorry, let's not make this any harder than it has it be" I keep trying to get the truth but the person won't give me any answers. I decide its for the best just to forgive the person and move on. This event has been haunting me since the it happened(about 2 months ago). In hindsight this person was probably a guy. I honestly feel horrible for letting this happen to myself. I have made sincere repentance with Allah and I believe he has forgiven me. I know some people who have had past relationships and say that when they get married they always have their first relationship in their mind. I'm not a saint, but I do pray my five prayer, try to listen to Islamic lectures and I think I am a kind person to a certain degree. I haven't don't any major sins( I don't drink, smoke or anything crazy). I made one mistake in my 18 years on this world which I deeply regret. The thing that is concerning me is that I'm afraid that this will affect my marriage and I won't be able to love my wife as much as I would have If this didn't happen. Am I still pure? What do I do? If I completely forget about this will I have a good marriage? I want to be a better person, but I don't want this to haunt me for the rest of my life. please help me. Any response will be greatly appreciated.



TLDR: I met a girl online and after a few months I found out she wasn't real. It was most likely it was a guy on the other end. I haven't don't any other major sins, I repented for doing something wrong. Will this haunt me for the rest of my life?
