In my opinion, to forgive someone after they cheated on you, you will need to calm down and be willing to forget about the incident. You should be willing to work on your trust and building a relationship that is closer or making a tighter bond with the person. At the same time, you can forgive the person and move on with your life without them. Whatever you decide, you will need to be sure you come to terms with the situation and spend some time thinking if you can put what happened behind you or not.
I can tell you from experience that once the trust is broken in a relationship, it's really, really hard to get it back.... and in fact.... even if you manage to rebuild the trust, it just might not ever be quite the same again as it once was. There's an innocence that's been lost; plain and simple. It's very sad. Anytime we feel betrayed by someone we loved and trusted.... can it ever really be healed? But you've got lots of options. You could close that door and give yourself time to feel sad, and then just go on with your life. You'll meet someone new, that's pretty much for certain. Especially if you're young. You'll meet someone new and you must allow yourself to be open to the possibility of falling in love again, and trusting again. You mustn't put up walls to try to protect yourself, because those walls will end up just caging you in and isolating you. So for sure... let yourself love again... even if it means loving someone completely new.
True forgiveness is NOT what most people think; forgiveness is FOR the VICTIM. it is NOT for the offender. when you forgive, it lets you free from all that horrible control the sin against you had. to forgive is TO ACCEPT THE CONSEQUENCES OF THE OTHER PERSON'S SIN AGAINST YOU...AND IT GOES FURTHER. IT MEANS YOU WILL NEVER USE IT AGAINST HIM or BRING IT UP TO HIM. forgiveness is difficult to do. it does not mean you will forget....it does not mean you will go back to him unless you want to. it does not mean you will ever, ever, ever trust him again. it means that you accept all the pain and cmbarrassment it will cause you and you will not hold it against him. that is huge to do. God bless you. and forgiveness is somethng you mght find yourself reminding yourself about...."I am so angry...but I forgave him and I cannot take that back...so I must find a way to live with this"
EVERYONE lies at some point some bad, some good. The reasons behind it may NEVER be understood by others but will stay true with the one giving the lie. With everything you have known towards that person who lied to you. YOU be the judge of him for he DESERVES whatever is coming for him since lying is NEVER GOOD.
FORGIVENESS is something EXTREMELY HARD to do. For it says"I ACCEPT that i have been hurt by someone by lying to me, and i will forgive him, but it does not mean I will forget, but, it is to say that I have come to terms that not everyone is PERFECT and that person deserves to be given another chance just like everyone else who has done a something wrong in the past"
Well you see that's why I say short relationships won't ever work!!! I'd say don't forgive him just get him out from your life and be patience till you get married...because the one who'll propose to should be your true love :) Stay straight n' virgin :) Have a nice day :)
