Can we really forgive someone?

Have always heard that forgiving someone is for us to heal..when we forgive someone, we are at peace ..we do that for oursleves more than the other person

But i always wonder can we really forgive someone  no matter how much that person has hurt us .
I mean its so easy to tell someone to forgive…but do we even realise the pain that person has gone through..everyday dying a new death..the trauma..the heart burn
I know its good to forgive,it brings u inner peace and calm…but again when at times u remember all those horrible times the pain comes ghusing back
People say its always good to forgive and forget…forgive ok…but forget..i dont think so…
To completely forget what someone has done to u…physically/mentally….that is i feel impossible to forget.
So i feel we can forgive someone but the pain stays with us…it nevers goes away

So on that Note May God give us the strenght to forgive someone..cause only the strong can forgive ✍
