Am I wrong for being upset?

Me and my bf were together for 6 years, have a 1 1/2 year old together. He went to the strip club with his friends one time and ever since then he became OBSESSED WITH IT. I think he literally developed an addiction because he was going there at LEAST 4 days a week, spending thousands of dollars on the girls there, he started literally stalking the girls there. I found evidence on his phone, very creepy evidence like him waiting outside the strip club for them to leave, taking pictures of them as they left and inside when taking pictures of the girls is prohibited there. he even found out where one of them lived. He was saying he was going to marry the girl even though she has a boyfriend and a baby. he even bought weed off one of his friends so he could sell one of the girls weed super under priced to impress her.

I broke up with him obviously after a couple weeks of this, at first I didn’t even know he was spending all this time at the strip club. I thought it was just once but nope, he became literally obsessed, super creepy and stalking them. What pisses me off is that he has spent thousands of dollars on these girls but has never given me a cent during our 6 years together. And it’s been 3 months since this started and he is still spending thousands on them a week and he hasn’t given me a single cent for our child. It honestly just makes me sad that he cares more about strippers that are only doing their job and don’t give a fuck about him than me and our son. Our relationship ended over the strip club, over people that only talk to him because it’s they’re job and because he gives them copious amounts of money. Am I wrong for being mad about this? Am I wrong for being upset that he’s giving them so much money but hasn’t done anything for our child in 3 months? also I should add I am going for child support I’ve just been super depressed and not giving a fuck for a while, working while taking care of my child on my own but now I’m just pissed
