Hello Masopaul, can we offer you a warm welcome to the site and unfortunately we don't know of the situation you have mentioned, but when you apologise to someone may or may not be accepted by the person the way you had wished it to be said, as it may not include any previous comments or how you have behaved to them before, so it's only for what's just happened so they are still unsure whether or not you want to be friends again or just saying you're sorry for now.
Apologising to a person doesn't necessarily make you friends, it's just being polite for what's just happened and it won't guarantee they will agree with you about something in the future, so a physical distance is placed between the two of you.
If for example there's a close friend I speak to every day but have made a comment which doesn't please them or they can possibly don't agree with and then apologise, this can affect our relationship from being close to being distanced and losing contact with.
Then there maybe a situation where you feel guilty about what you've said and they accept your apologies, but you can't understand why, then isn't this true friendship, we can't always agree on everything, even if you have a twin.
Accept how they feel and the more you query their decision only creates a hurdle for you to jump, one you may not have to do.
