Hi. I'm nearly 5 months pregnant and still not completely over my ex even though I'm pregnant with someone else's baby. I'm now gonna be a single mom & recently found out my ex is playing step dad to his new girlfriends baby I think she's about 3. (We was together for 3 years & his been in this new relationship for 4 months) we recently met up and spoke just as friends and I felt fine.. now I can't stop thinking about the fact I miss him. What should I do? How can I be at peace!
