HELP!!!!Seriously need some relationship advice...?
Remember something, if ';love'; is still there, continue it. Don't call it force, it's just trying to solve the problems in relationship to continue it. Ask yourself what's the problem that caused you and her to be like this? Talk to each other about it, compromise, keep on trying and never gives up! Even if this time you both have tried and failed, there can be another next next next time to retry. Don't limit to yourself that ';if this time, it didn't work, we'll just end. i'll give it only once';, because if you love her, and she also loves you, I think you guys should just try forever. Don't care about anything as long as you guys still love each other, fight for it. Fight with the problems until you both could win it and you'll know that problem is just a part of every relationship, friendship, family etc. cherish your love cos it's not easy to find someone who truly loves you%26amp;you love her as well. But well, if you both don't fight and just looking for a goodbye, then don't call it love. Good luck.Seriously need some relationship advice...?
Only you can decide but if you are apart for a while it will not be possible to stay faithful or believe the other one is being faithful - I would move on and remain friends, in the future if it is to be then you can try again
