Hi, I am so hurt right now and confused.
I agree with the other posters. He didn't tell that girl he had a girlfriend who he loves dearly. What did he tell her? - something that would make the girl think he is single. Along with exchanging numbers, well... "duh!" It's pretty obvious what he was up to.
Sorry. I know you've already established a life with him but it appears to only be in superficial ways. You can reestablish yourself without him easily. This man is not worth keeping around for the long haul.
Do you believe what that girl said? Because for me it is not that he messaged this girl but the fact that he said how you two broke up. For me that is a sign that he was hoping something will happend between him and that girl, why else would he lie? Just think about it this really hard because I know you love him and you want him to change but what he did was so disrespectful.
And also how will you trust him in the future? Do you really think he will stop or will he just get better at hiding it from you? Do you know why he is doing this?These are things that you need to think about and also speak to him about.
Problem is that we women usually do not get out of the relationships when we should, we tend to linger and hope that somehow miracle will happen and that he will change. But years go by and nothing changes and then we look back thinking why we did not get out on time. You might have invested a lot into this relationship but imagine if you stay
