Cheated!!!!! Possible child involved Long Post!!!!

Ni

So my S/O I've been with for 9 years cheated earlier in our relationship, but I choose to forgive him. 4 years later I find out through our phone bill and records that he has been contacting her again. She has the same number. Now he goes to work and come home every night, claims that's the only thing he does. Now one morning something told me to check our call logs online again and come to find out he had just called her right after he left the house to go to "WORK". Then he contacted me right afterward like everything was cool. Sooooo, I didn't confront him at the time I decided to be petty as some call it and contact the girl. She told me yes there still messing around, and that he would always tell her that he worked off shore whiches the reason why he didn't see her as much and he wasn't with me anymore. 🙄 anyway we met up, and she showed me all of his messages from his recent number and previous number because he had gotten his number changed. As well as a picture of their child they supposedly had together. She let me listen to Voicemails he would leave saying he wants to see his son and he misses her etc.....,at this point I'm heart broken once again. So when I finally do confront him he's stuck for words,, and he denies the child. I also let him listen to the voice mails about wanting to see his son etc... and he still denies him. I asked for a paternity test that he refuses to take. Now I didn't not mentioned earlier in this post that we have a daughter together and around the time me and the women he cheated previously was pregnant at the same time. He also was upset when I told him I was pregnant and wanted me to abort her sooooo bad and I didn't I just told him I would leave him before i killed my child,,however he decided to change his mind about the abortion,, rather he did not buy our daughter anything to help support from newborn till about two yrs of age. It's just a disgusting feeling. Out of anger I was getting even pettier by calling him and clicking her in on three way for her to here his lies,,, and he kept calling her bitches and saying all kinds of disrespectful names. This post can go on but let me just get some advice from anyone who has experience with this type of relationship. PlEASE BE HONEST.... I can handle if I was being childish a bit.... but at this point I need advice.....
