Romance/two couples sig others cheat with other, remaining two become friends/date

[Sumeya]

Unfortunately I haven't read the book, I really want to but can't remember the title. It's about two couples that live in the same neighbourhood and I think are friends. The guy from one couple and the girl from the other cheat with each other and end up leaving. So the remaining guy and girl become close friends visit each other often and the girl was pregnant so he helps her during the pregnancy and then with the baby after it's born and they eventually become a couple. I don't know when it came out but I think it's pretty recent. Read the summary somewhere in the past 2 or 3 months. Please help me find it, it sounds so cute, I don't know how I didn't write down the title somewhere.
