Is there a certain timeframe you and your partner should go without sex?

Last time I saw or had intercourse with my guy was 3months ago!! We have made plans that never happened. He has said work, over time death in family busy as excuses! He said just because it's been time doesn't mean doesn't want me or love or like me. A few times there has been some ghosting, ignore calls or text. I understand we all get busy but 3 months seem like way too long. If you miss something or someone you make time was and is my thoughts. Need help.
