I need advice

Ok ladies I need some advice. So I'm 5 weeks and 3 days pregnant the father of the baby is just my friend and we conceived on a drunken night (not a proud moment of mine) I have two kiddos already age 4 and 2. Well I have been talking to this amazing guy who is amazing with my kids I told him as soon as I found out I was pregnant so I didn't hide anything from him. He told me that he wants to be here for me and my kids the best way he can. He wants to move into my home and all this stuff already and wants to be together. I'm flattered and all I just don't know what to do. I've been so moody lately and I hardly want to be touch and he is constantly wanting to hug and kiss and hold me which is so nice but I haven't been in the mood and he has been so understanding of it all. He just recently before we started talking a month ago got out of a 6 year marriage due to her cheating on him. I feel like he's moving so fast and I'm unsure of what to do I really like him and he's been wonderful with my children and so understanding. Advice pleaseeeee
