I’m so mad that he lied

I need your help ladies I have no clue but I need your opinions ... sooooo my bf and I unexpectedly had a baby last year at first he wasn’t for it and got pretty upset ... now he loves out daughter so much and supports us 100%. Today I just realized something...

He keeps on saying he doesn’t want anymore kids yet he cums inside me every single time we have sex and we have sex multiple times a week.. i also told him please try not to cum inside or let’s wear protection I have never gotten pregnant throughout all those times and mind you he’s probably came in me over 100 times. The time I did get pregnant he only came in me that one time every other time before our daughter was born we used condoms now he seems so carefree not even scared to cum inside. Today I am so suspicious of why I haven’t become pregnant then I look up “vasectomy” I had no idea what this even meant until today and now it’s all comming together.

Last year a little after he found out I got pregnant, he told me he injured himself at work lifting heavy things. He said it was something called a hernia surgery bc he pulled a muscle in his scrotum I don’t fully remember but it was something like that... he used to complain and say it hurts and he neeew to go get surgery soon multiple times and finally he made an appointment and it was surgery time I ddnt really pay much attention to the whole thing he missed work for a week and went back after a week and we had sex th same week he had surgery now I look up both vestectomy and hernias and appearntly u cn have sex a few days after a vasectomy (which is what we did) I r,ember that day it was still healing and he showed everything the incision area which was made on his balls where a vasectomy is made ... a hernia is made above th pelvic bone ? Please can somebody correct me if I’m wrong now I feel like he lied and said he got a hernia procedure instead of the truth which was going to get a vasectomy I am pretty mad and sad that he would go and do this without telling me I know it’s so,etching personal but wtf what if I want more kids in the future I don’t know somebody please let me know and I really want to confront him about lying to me about it but not sure if I am wrong and if maybe he did get a hernia procedure is there such thing with a incision on your actual balls because that’s where I saw the stitches

UPDATE

OK SO I ASKED HIM AND HE SAID HE DEF DID NOT GET A VASECTOMY AND THAT HE DIDNT EVEN KNOW WHAT THE HELL THAT IS AND HE IMEDIATLY LOOKED IT UP ON HIS PHONE INFRONT OF ME SEEMING SO AMAZED THAT THERE WAS SUCH THING... HE WAS LIKE OMG WHY WOULD I GET SOMETHING LIKE THIS IF I DID I WOULD JUST TOLD YOU BUT WOW HOW MCH DOEE THIS COST I WANNA LOOK INTO IT CS ITS INTERESTING AND MAY BE JNTERESTED IN SOMETHING LIKE THIS BUT WHY WOULD I DO THIS I DEF WANT KIDS IN THE FUTURE ?😒😒😒😒😒🤔🤔🤔 hmmmm still I do not know if this is an act ... he kept on going on about his hernia pain and hernia procedure
