So my Partner (20/M) and I (21/F) have been in a relationship for around 1 year but recently I have realised he have lied about his past regarding his dynamics with his friends. They used to flirt while he told me it was one sided from his friends I came to know he was a party to it. He has continued friendship with them and told me all this time that he never reciprocated their approach back then. I found out through his Instagram that it was a lie.
Moreover, we had a conflict when he violated a hard boundary I put forth about not interacting with sexual content on social media. He liked something a friend (20 F), lets call her T, of his posted and I expressed that it makes me upset. I also explained I have no issues with their friendship its just that he has to respect my boundaries if he wants the relationship to work. The issues with this T continued as she would ignore me or refer to me in a condescending tone while talking to my partner even when I was there. I was upset with him not standing up for me and after this he made the decision to ignore her. I was against this idea since they have known each other for the last 2 to 3 years but he insisted. Later I found out that he told her a different story of me accusing him of messing around with girls and that he was ashamed of his actions (that he ignored T) but he had to since there as been conflicts. He also shared some personal information of mine which I even asked him not to tell her. She naturally sided with him and said she won’t talk to him in campus to avoid conflict.
Now he is trying to say the chat with T doesn’t look like it really is. That they don’t mean the literal meaning when they say “messing around” and that she has a big mouth and would have spread rumours about our relationship since she us during a conflict once. He says he told her all this and then called her to tell her not to share anything of whatever he said and about anything she has seen.
My point is, even if I accept that whatever excuse he is giving is true, he didn’t need to make me look like the crazy controlling partner just to stop her from talking about us. He is asking for a second chance and wants to start over. He apologized for everything and said he won’t do it again but the interesting part is he deleted all other conversations with her before I could see it.
Tl,dr: Partner lied about his part dynamics with his friends and lied to another friend about how I asked him not to talk to her.
Should I or should I not give him a second chance?
I apologise for any mistake, English isn’t my first language.
