Wattup fellas, first time posting so go easy.

I'm 23, Indian, living in London and got out of a serious relationship 6 months ago with a girl called laura. After the relationship my parents with my permission started looking for a bride for me from back home. They found one, a good cultured girl, 0 partner count, pretty and young, we'll call her sonya. 2 months into talking over fb and whatsapp and I'm flying over to get engaged. At the time I'm thinking this is a good move, marry a good girl and have life set out steadily. Meet the girl, we get on well but theres no real connection, she can't relate to my life and I'm the same with hers, i decide to get engaged anyway thinking we'll establish a connection over time.

Come back to england, keep in my mind I'm still hurting from my relationship laura since i have crippling oneitis for her, i text her a few months in when I'm back and she wants to meet, she's seeing her boyfriend still but comes out to meet anyway, we fuck for about 2 weeks(she dumps him after our 2nd meet) and she starts pushing for commitment, i refuse saying i dont trust her yet and my minds in 2 places about the marriage, she says fine we're still working it out.

A couple of days ago she starts acting weird/distant when like 2 weeks ago she was obsessed with me. I start to realise wassup and play it cool, yesterday she meets up with me in the day and we sort a plan for the night, she's down. As soon as she leaves she texts some bs excuse about how she has to look after her nephew last minute, at this point im super suspicious but say thats cool, she offers an alternative to meet a little earlier just to hang, i say okay. She comes and smokes a spliff acting weird still and then says she has to go. I decide to bait her and text her that night asking if she wants to hang, she refuses and wants to go to bed i say okay. I drive to her house and her cars not there, drive to the nephews house and the car aint there. At this point i know she's fucking around.

She texts me in the morning blatantly lying to me how she was so tired blah blah, i ask her what time she got in, she said 10 even though i was at the house at 1 in the morning.

Now im pissed, this bitch tryna take me for a dickhead, so i confronted her and told her to tell me where she was at. After what seemed like a hundred lies and a fountain of trickle truth i find out she went to go see some other dude who she buys weed off who lives in another town about 20 miles away who shes known for like 2 weeks.

I was gobsmacked, couldn't believe it, felt disgusted by this chick who was whispering sweet nothings into my ear a week ago lied in bed and now she's out getting dick somewhere else, wtf! I dropped her telling her I'm seeing other girls too and it looks like we're playing the same game (even though I'm not) and she proceeds to block me on whatsapp.

Guys i know i fucked up on different levels but i had to write this shit out because it's eating at me. I wanna know why the fuck i feel so hurt over this and what can i do to get over this?
