I've never fought with my boyfriend, we have been dating for two years and a few months ago he did something that really hurt me. We messaged about it and at first I thought it was solved but, after these months I can feel the injury is still aching. I don't want to bottle up this feelings anymore, every day they are getting harder to hide, but I also don't want to screw up what we have right now by bringing this past issue onto the table yet again. What should I do? Any ideas or advice are warmly welcome.

You've got to talk about this issue with your boyfriend. If you don't the feelings you feel now will only amplify until it becomes to hard for you to bare. But when you bring it up, it has to be from a 'I want to resolve this so we can move on,' and not a 'you are making me feel bad and you need to fix this' standpoint. Remember, Its you two against the problem, not you two against each other. You're stronger together.

Thankyou very much for the advice. I think you're absolutely right. I'm scared of talking about this directly but now I realise it's the healthiest and smartest way to solve this once and for all.
Thanks again :)

I just want to repeat what this person said. I struggled with this for a very long time: I have been dating my girlfriend for two years and we have only fought twice. I've been given this advice before and the issues only resolved themselves when I followed it. So good luck and I hope that it all works out for you.

Thanks for the reinforcement on the advice. :)
I'm just scared that after discussing this our relationship might get awkward or worse... we could start slowly to drift away.
Did something like this happen when you discussed this with your girlfriend?
Thanks again
