Ok im lost i need advice ! Im married for 17 yrs i have 6 children

Ok so like for approximately 2 yrs back till now i been having a lot of intimacy problems with my husband,he doesn’t want to have sex with me he’s always tired or put millions of excuses to avoid it and when i finally think i convinced him he only cares about me having an orgasm and he doesn’t mind if he doesn’t 😣 or is so hard for him to focus sometimes is not even worth the try ,almost all the time i feel im not atractive to him anymore he always say he loves me and everything and hes always here and leaving his phone everywhere so is hard to think he’s cheating,he gets upset every time i bring our intimacy to a conversation and he tells me now our love is different but how i still want to have sex with him 😞
