Is he cheating? 😪🤷🏻‍♀️

hello ladies long storie sorry but need some king of advise! 🤷🏻‍♀️😅😭 I just want your opinion about this....so my husband and I are 9 years married (not kids). He was as far as I know super in love with me...he doesnt tend to go partyin or with friends without me and we are almost always together...he still care about me but this past 3 or 4 months he is acting different, 😪 not sending me texts while in work but still respons my texts or calls....is just that I feel some kind of lack of interest to my persona neither that exciment while having sex...(I use to make him come so quickly while being on top of him and know seems so difficult to have him into "mood"...) he abviosly says im crazy and that he is sometimes tired from work , also have to mantion that latly he spend a lot of time in his phone sport gabeling and his mind seems occupied in somethin else rather than me (he really sleeps less and have to drive a lot in this new job but i think every man wants sex maddly at any time 🤷🏻‍♀️🙈)  last thing happened yesterday, he repost my insta storie but hide my name (my @) and said that he did it cause he have new followers from work that he doesnt want them to look at my page...but guess what? I checked and he does not have any new man followers....so for me this was like other red flag?🤷🏻‍♀️

i know he have new  responsabilities at work and etc....but why this lack of interest or for me? am I going crazy or could this be just because he is "super tired"?....but hiding my name on the insta I did not like that...mostly because he wansnt like that!!...so I have the sensation that he is into someone new...I dont know if giving up my marriage just becaise of this or not 😪
