So a very long story short...
4 years ago, i meet a girl, love her to bits, was in my teens back then and very naive in dealing with relationships. However, me and this girl used to hang out, go for cinema, go for meals, etc. Eventually we dated, it never worked the dating, we never had sex, hardly even kissed, things were awkward, but the whole time, she was texting this other guy, and getting pretty close. At the time i had no idea, and she started to ignore me more, delay plans more etc, but like i said, was naive and paid no attention, just loved her. Which stupidly left me alone, hurt etc.
She started dating this guy, i did my best to move on, and few months after i found a new girl, was with her for under 2 years and had a great relationship, never any trust issues, no arguements, was having sex and everything was great.
So this first girl, (who i always had something for all along) gets dumped by the guy she was with, 3 months on, the girl im with no longer wants a relationship with me, and once again, more heartbreak for me.
1 year on, i start talking to, and seeing the original girl again.
I've now been in a relationship with her for 4 months, but i've suddenly just really started to think deeply about 4 years ago, and how she betrayed, lied and made such an idiot out of me and all the hurt i had.
It feels like in the whole long run, i'm with her, i'm second best, she doesn't treat me like second best, even sometimes randomly mentions when i'd be wanting kids and marriage, and says she'd always want her life to get more serious with me, our relationship so far has been good but im feeling a little off with it last couple of days, i love her, and nothing i feel will stop me loving her.
But i can't stop thinking about it when i sleep, wake up, eat, and last couple of days, one minute i send her a nice text, and the next minute i think back to 4 years and pick up alot of hate for her!
How can i forgive? do i need to address this with her? i feel i need it in the open but dont want any confrontation or arguement about it really. I hate sounding jealous, and i'm quite the opposite of a controlling guy.
EDIT: sometimes she mentions her EX, wouldn't say talks about him, but just throws him in conversation sometimes, and i have no interest whatsoever in any part of any story/history she wants to mention him in. With dutch courage i've even asked her if she has anything for him still, she called me silly and said course not it's me she loves, and that shes shocked i'd even think that, but..
