HELP! Is this acceptable in a relationship?

So my husband gets mad as hell and jealous, whenever i listen to guys sing on youtube, or subscribe to a guys channel. Hed act like im into them more than him, and that i should only have eyes for him, ans i should only want him. Stupid ik.

Back in 2015, i told him to download the smule app, so we both could sing together, ans he didnt give a crap about it. Til this day, he began using that app. Hes following women on that app, and doing collabs with them.

Now, im making a big deal about it, cause i know that if i was the one following guys, ans doing collabs with them, he wouldnt like it at all! So why is he even doing it? He thought i deleted my acct, so he thinks its ok, as long as idk about it. And its no wonder why he never wants to show me or listen to his songs on smule.

After he did those collabs with other women, he began to act affectionate w me, all lovey dovey, when all this time hes been ignoring and distancing himself from me. Hed use the smule app for 10hrs straight! I havent confronted him about it, but i plan to.

Even i cant have guy friends or interact w them.

Am i wrong for making a big deal about it?
