I met this guy 2 months ago, he moved in with me about 3 weeks ago.We fell in love right away I have 3 kids of my own and he has one child but doesn't see him because of personal issues with his ex... now after living together he says that it's a little hard for him since he's never been in a relationship like this.. it's his first time.. but we love each other.He is trying his best to adapt to the relationship and my three kids which he love very much.What should I do for this relationship to stay strong and not fall apart.

You met a guy 2 months ago and already he has been living with you for three weeks. If I did my math correctly you dated a guy for 5 weeks and moved him in with your 3 kids. Not smart. Also the man has nothing to do with his own child. I would think twice about this living arrangement. You are already concerned and you should be. Move him out and build your relationship with him on a slower pace. Think about your children 1st.

We fell in love right away. But we love each other. My 3 kids, which he loves very much.

None of this is love this soon, it's infatuation and romance. Love comes only with TIME.

You aren't giving us one clue what might be wrong, but I'm going to guess: he doesn't 'love' having 3 instant children who aren't his own nearly as much as he says he does, and as the romance fades a little bit, and he's expected to help out, and the kids are running around and needing things and spilling soda and changing the channels, he's starting to wonder if it's all worth it to have you.

What I'm having a hard time understanding is, how you barely know this guy (trust me, NO matter what, even if you spent 24/7 with this guy for 5 weeks, you STILL barely know him) and you brought him into your home... with your children.

I know you obviously must think he's a nice guy and all, but... moving in after 5 weeks is absurdly fast, especially to put your children in that situation. If they're older, then I'm mistaken and I apologize. But all of a sudden, your children barely know this guy and they now have another authoritative/father figure in the house. That's got to be very confusing for them.

Move him back out, and slow this train down. WAY DOWN. How old are you, and your kids? Seldom is there instant success when you move this fast.
