I don't even know if its any of my business or what I should say. Basically Sam has a new girlfriend (according to facebook) and I don't know if it's a good idea. His ex cheated on him a couple of months ago and left him heartbroken. I last talked to him a few weeks ago and he said he couldn't be with anyone for a long time because he's still in love with her
I am worried that he's going to fall back into what he had with his ex and it will all go belly up again. I don't know this lass and he hasn't told me himself yet. Do I say I'm pleased for him that he's moving on or that it's too soon or it's not a good idea?

I don't know what I think to it to be honest. On the one hand I'm very happy that he's moving on and forgetting about Becki but I also know that he's not forgotten what she did to him and I'm worried it could be a bit of fun that is going to hurt him more.
I'm not in the habit of telling people what to do but I am concerned given what happened in his last two relationships and what it did to him. I know he's not over Becki and that he can't have a no strings relationship. It's either all or nothing.
Maybe he hasn't told me because he's scared of my reaction. Usually when he's had a girl or gone on a date he'll tell me the next day (whether I want to know or not).
All that said, I miss him immensely

Maybe I'm slightly jealous because I've been thinking of everything that happened between us. But I don't want him and I never did. So jealousy doesn't even come into it.
Maybe I'll just wait for him to tell me then base my reaction on what he says
Edit: Sorry for the long ramble. It's been whizzing round my head since I saw it and I just don't know what to think of it.
