I personally feel that if a relationship is making u a better person and leading u in the direction of your progress, then its worth keeping…
and if not, if its leading u in the negative direction and continuously leaving u with varieties of negative thoughts and feelings, then u are not in a healthy relationship…

okay, so both of u have broken up…

Now u are left with loads of feelings, specially negative feelings, to tell her about what she had done… but u are afraid that she could do something bad, or harm herself… so leave it… don’t think about telling all this to her.., u are doing it right…

So, first of all, don’t be harsh on yourself…
you have done nothing wrong…
we can’t control each and every situation…
you have tried every thing you could…
and you have done your best…

but evrything still remained messed up… so just leave it (i know its difficult),and don’t blame yourself…

I know you have many questions about all these situations and their results.., but don’t worry.., keep patience.., everything will make sense at the right time…

You just have to wash all these negative thoughts off from your mind to see everything clear…
and they are also not your mistake.., situations just happened and they trapped you…

But now it’s you, who have to choose not to remain trapped by these negative thoughts any more…
don’t believe them… fight with them.., each of them are rubbish… they don’t make any sense… the are useless…

Focus on the positive things, (except the things related to her) this is obviously difficult.., but u have to fight na… force yourself to focus on positive things… at least for some weeks, stop focusing on her and start focusing on yourself, and wash your mind..!
I mean to say, clear your mind and replace all your negative thoughts with positive ones…

But be gentle on yourself.., do whatever you like…
the best thing,as i feel, you can do is go for a trip… go on a small vacation.. and try to enjoy and experience each & everything there… this will surely clear your mind… and you will be able to see things more clearly…

God bless you…!
