Will my deeds be rejected because of the animosity between me and those with whom I quarreled, even though I have forgiven them and am ready for reconciliation, and bear no grudge against them in my heart?

May Allah congratulate you on making peace with those with whom you quarreled and not holding grudges against them. You should continue to respond to their ill-treatment with kindness. If they persist in shunning you after that, then you are absolved of sin and they bear it. For the best of those who dispute is he who initiates peace, and this is what absolves one from abandonment according to the majority of scholars.
