I just need to rant

I found out last week my boyfriend of 5 years is vaping he has been since march.He know i dont like smokers or vapers when we first started dating he was smoking but kept it from for about 6 months when i found out i was pregnant with our first child. If had known he smoked i wouldnt of dated him. He did stop smoking a little after our first was born but started again about 1.5 years later and kept it a secret from me and i had only found out when his dad told me. I fell pregnant again with our second and he stopped when he was born as we was stuck in hospital for 5 day and he wasnt allowed out our room coz of covid. He did so well but started vaping when my second was 1 year old i found the vapes in his bag he had been vaping for 4 months then. He did stop and started back up this year in march. He started being very secretive with his bag i wasnt allowed to touch it or clean the car out. I knew he started smoking or vaping but when i asked him a coupl months ago he lied to and said he wasnt and started shouting at me. Then 3 weeks ago a vape fell out his pocket and lied to me again and said it was his friends i knew it wasnt i knew it was his but i was so upset he lied to me. Then finally he told me last week he is vaping and only told me because his dad caught him and he had to tell me. I dont know why he kept it from me for so long and constantly lie to me and gaslight me when i ask. I dont know whats going to happwn going forwardin our relationship. I cant trust him no more and i dont know what else he is lying about
