Can you get your ex back?

[getexbackorlethimgo]

I screwed up but really like my ex. He feels unsettled, lost trust and never really had a chance to fall in love with me before I did really stupid things, being needy, chasing him etc making unrealistic demands based on his level of feelings (wanting commitment)

I never did anything terrible. There's not really any reason for him to dislike me or lose trust but it happened. What do you do? Give up all hope and move on or do the whole no contact reattraction thing... does it ever work?

You can't do anything except accepting it's over. Get on with your life if he wants to come back to you he Will, if he doesn't want to he won't, you can't make him feel something he doesn't.
I would concentrate on working out why you were needy and why you acted how you did, there may be under lying reasons why you feel this insecurity in relationships and until you deal with that you will keep on making the same mistakes. Whether that be going for emotionally unavaklable men or ruining a potentially good relationship by being needy and demanding.

He is entitled to feel the way he does and to not be in a relationship with you. NC isn’t a ploy to get him to miss you, don’t compound whatever mistakes you made whilst being together, by engaging in game playing now that you’re not.

Think it’s a lost cause. Move on

Only if they really want to come back. Otherwise you are setting yourself up for heartbreak.
