Boyfriend problems...

So I caught my bf texting two different girls. One was saying I can't wait to meet his daughter and asking him to call her .. well I confronted him about it and all he said was there was no girls well I had went through his phone cause I knew he was. But now he's ignoring me.. so I told him if he can't talk to me and stop ignoring me then I'm packing my shit. So he said then go I'm not going to be accused of anything I didn't do. I don't want to leave but I don't want to feel like I'm being cheated on.. should I fight for it or just leave
