Dating

Any advice welcome?

I'm looking for advice I was dating somome for 5 months at tye start he was talking to somoke else he was open about that then said he stopped talking to her whuvh I found out was lies ao for the 5 month 3 of them she was still there while I was loyal

I was very upset by this as I felt disrespected and I left things with him Monday night I was very upset as 5 months all day everyday talking

And yesterday I did not even get a message to say hope your ok nothing and I just feel he's a heartless person I obviously didn't mean much I don't think he realised the damage he has caused by lying and making me feel the other girl was gone while I spent my time etc on him and him only I told him least my conscience is clear as for him he will have regrets also said he loved me vut wa messaging the other girl I just feel a idiot tbh any advice on how to deal with this

Any advice welcome?
