Disputes arise where there is love and friendship. This involves lots of patience and requires resolutions. Speak with him in detail when things settle down. Do not ignore anyone just because he/she is not having a good mood or having a difficult time. If I am not wrong love is based upon trust and loyalty. So here are few suggestions: 1. Go out for a meal (dinner/lunch) and talk; 2. Give him a gift/present and talk; 3. watch a movie with him and talk; 4. Go out for a long drive and talk; or 5. involve a neutral friend who is close to you both and talk.
