Help. Want a divorce and want to go back to my first wife. Help MESS?

Please dont laugh at me. I'm really miserable right now. I'm a 25yr old male, and am on my 2nd marraige. First I got married at 19, had a baby, split with the mum at 21. Two months later i met a woman i thought was the love of my life. Within 2 months, she was pregnant, and we have a fabelous daughter together. But we split, i realised i was growing up faster than her and that the relationship wasnt right. Then i met another woman, but we didnt have kids. Then Last year I met my current wife, we have a baby 3 months old. Look I love all my kids and they are all really well supported. However, i'm just so mixed up. Life sucks right now. I'm back in touch with my first wife, and we have been sleeping together, now she is 'late'. I'm just so worried. However, I feel a real connection there. Maybe i should have stayed with her. But when i was in that marriage i felt trapped. I'm now getting therapists opinions. I've been to 3 therapists. One told me to work on my marraige. One told me to take time out on my own. One told me to go with my gut. I'm spending a fortune on these shrinks and my lifes still a mess. Please tell me what to do? I'm so worried.
