No judgement please

Hi lovely ladies, no judgment please. Me and my partner have been dating 3 years. The first year like anyone else was great, we slept with each other quite a lot, 2 even 4 times a week sometimes. It slowed down after that and we went through some rough stages with him flirting with girls and some suspected cheating. I know I shouldn’t have stayed blah blah blah but it’s more complicated than anyone else knows. Anyway we have been going quite good the last 8 months but the sex has almost stopped. We don’t have sex maybe only 1 maybe 2 times a month. No he’s not cheating anymore definitely trust me I know. But my sex drive is very high. I’m 6 years younger 24, partners 30. Is this normal or not? We both work and run our own business. Bit stressful yes of course and like anyone else we do fight. How do I get it back. I try and instigate stuff but I do sometimes get shut down. What can I do please help... super horny at times.
