need a little advice!!!

I'm going through a horrible divorce but I've accidentally met a man that's awesome. By accidentally I mean like I wasn't going out looking for a partner or anything. Me and this man I met are so compatible it's ridiculous. Only downside is this man has 6 kids 😞. I'm only 21 I sometimes fight with myself and say I can't do it but the mom in me says I can. I have one son and lost one in the womb. I've always wanted a big family and I'm pretty sure I can't have anymore angels. I'm really torn in between my feelings and need some advice as to what would be best. Thank you in advance !!!
