So my boyfriend, 16 is best friends with his ex. I know he was pretty obsessed with her before and he was pretty hurt when everything broke off. And he said he was ‘too nice’ to become friends with her again, but he did. And their ‘best friends’ right now. Yesterday, he went swimming with his parents but she ended up being there. He stayed longer for her, but he knew I was going there with my family, and didn’t bother staying any longer because he may have been picked up. Also, he spoke slightly in the pool but just said had fun and left. Is it normal and okay for him to be swimming and out with his ex-best friend? Even it’s a coincidence? I do trust him, completely and we are both madly in love. But it still worries me that some flames might be ignited. Help, please.
