My marriage is over

I think my marriage is over, I have issues with insecurities because my husband cheated on me a month into our marriage. I did decide to forgive him but some things still bother me. Which I don't think he had done anything since then but I'm still hurt and I still don't friar him 100% and he is tired of it. So last night we got into an argument about it and it got pretty heated with me and him that my son jumped in and they got to arguing. My husband said some real nasty things to me and him and now I'm in between making him and my son both know that I love them both. I don't know what to do cause both of them have issues with each other. Could a marriage work when u have them both going at each other all the time?
