Do guys get confidence after losing their virginity?

because me and my ex started dating and

i wasnt a virgin and he knew but hated that detail.

well i took his virginity and hew was shy about it at first .then we started having sex alot.and then later on like five months deep into the relationship,he started acting all mean.and if he had something to say he will say it.and before he was a shy little boy.

and then when we turned like 7 months deep into the relationship he broke up with me and told me he needs to get into his studies.but later on like three weeks he hooks up with this girl and tells me she is nothing compared to me.i was like wtf?

and he tells me that he still loves me.(me knowing thats bullshit)
