My wife and I have know each other 12 years been together 11 and married for 2.... With that being said I really want to expand our family... We don't have the money to go through boctors but have found someone who's willing to let UA use his sprem and wants nothing to do with the child afterwords..... We have gone as far as picking out names for our kids.... But every time I bring it up she says the timings not right or that she wants to wait until we have this or that ect..... I am going to be 22 and I honestly want to have my first kid by 23 but I feel like she doesn't want any kids sometimes... What should I do or what would you do if you were in my situation or if you are in my situation how are you handling it?
