Thanks everyone, especially andy, andrea and leelapops, and tetjam your answer made me laugh but I dont think thats an option!! It makes me feel a little better to see all the support on here. I think I have been burying my head in the sand now I can see it written down in black and white and all the comments it seems very obvious. I love my husband and I think he loves me so it may be possible we might be able to work through this, but I'm not sure how I would feel once I have confirmation from him. Its been quite hard since I got pregnant and I did suffer from post natal depression and my husband has not handled any of this very well.
I cant check his e-mail as I do not know the password (yes, I've tried everything!!) and he keeps his phone in his pocket all the time and NEVER leaves it laying around (he has always done this though). I don't know anyone he works with so thats not an option either, also he does have lots of spare time to have an affair as he works shifts and I work full time. I may have to confront him again, but I'm sure he will deny it.
