He lied

A few months ago I got upset and went off on my boyfriend for texting another woman and calling her beautiful and he was stopping by her house when he was supposed to be at work saying he was getting weed for his friend he works with .....he went completely off on me and made me feel terrible because he said that this woman was an elderly woman in her 60's and he would never cross that line so like I said I felt terrible and I apologize for multiple times and I told him I would never go through his phone again I would simply ask him if I felt some type of way about something and for the past few months I have kept that promise despite any red flags which is why I went through his phone in the first place I've also continue to let him talk and buy weed from this lady.... Now this morning he tells me we were invited to her five year old daughter's birthday party I was shocked I asked him how old she is and now he is saying she is only in her early forties she has two children around the same age as my children and a boyfriend around the same age as my boyfriend ...and although we had worked this out previously I am very upset because he made me feel bad for believing what was really the truth and then made me apologize because he convinced me of something that wasn't the truth.... I can't believe he lied to me about this... I guess that's because I was going to leave him for it... but why can't he just take responsibility and accountability for his actions... Now I feel lost because even his mom took up for him the first time and convinced me not to leave him... And he knows that I don't like that kind of stuff, I laid all my boundaries on the line from the very beginning. and I feel like he just keeps crossing them and lying about it and then telling me I'm crazy for feeling the way I feel... After he told me there age we never said nothing else about it and and I didn't bring it up that he had lied to me previously and I'm not sure if I should this was indeed a deal-breaker for me and I don't know if I should just let it go or if I should call him out

This was their texts I also noticed he was deleting them daily.. and also I was picking him up from work that day...I don't care if he has female friends BUT I don't agree with him calling them beautiful and sneaking to see them while he's at work and deleting their text messages!

UPDATE : well ladies I asked him about it and all he had to say was how is he supposed to know exactly what age she is smh.... And I don't want to be with him but I don't know what I should do at the moment because I just found out I'm pregnant!
