Hey there, we all start this way, scared, wondering the other person is still around, waiting for the other shoe to drop, thinking all sorts of things. It's only natural you dont' trust him, and only time will help you build that trust again.
In the case he had someone, he might be weaning off that person and might have old txt messages he doesn't want you to see (same thing happened in my case, my H wasn't himself when he came back.) He needs time to get back in the right state of mind. After a separation the WAS have developed a different rhytm and life, give him time, coming back to you is another huge adjustment.
About the SL, it is always ackward at the beginning. My H told me months ago that it is odd moving from one R to another, he felt unworthy and guilty, and guilt is a major mood killer. The only thing you can do right now is to confront your fears (ow), decide to forgive your H and move on. The mental picts used to kill me, but no more, when I ML w/my H , 9 times out of 10 I won't think of them.
I know it seems hard but you will overcome it. The first months of piecing are the hardest, the wounds are still fresh and there is mistrust in both sides. Do not let fear overcome you, it is a delicate sich but you'll do fine. Forget all that nonsence he told you about not loving you, you know it was just MLC/depression saying that. I actually brought that subject up w/my H, and he did admit that he was happy, it is just that they need to justify their escape.
I always recommend this book "healing the hurt in your marriage", an excellent piecing book. Hang in there, it'll be ok. Dont' wait for reassurances from your H right now, he might not have any to give you right now, he might still be out of sorts w/himself.
Be not afraid...I will repay you for the years the locusts have eaten Joel2
