Ladies i need your help

Would you leave you boyfriend of only a couple of months if you found out that he was still texting his ex girlfriend and even said that they should hang out? She told me nothing has happened between them nor has he texted or talked to her sexual.

My issues is that the trust is broken and now my walls are up....all because he lied and only showed me what he wanted me to see via texts when it came to their conversations. Don't know what to do but as of right now I've broken things off with him. Don't have time for the drama...or stress. Kids are involved.

Thanks ladies
