Happy Wednesday to you M.!
You are VERY fortunate that your child's father is taking financial responsibility - you have no idea how lucky you are! I am going to chat with you on several different levels, 1: as a woman that was single for 14 yrs with 3 little ones ... and 2: as a "mother" figure.
You need to remember how lucky and blessed you are to have that little boy AND to have a father that is being responsible financially ... AND #3 ... to be intellegent enough to know that you need to be further educated to be able to supply your child with a financially stable arena to grow up in. I applaud you!
On the "mothering" part of my 2 cents ... you are so very young. It is far better for this man to realize NOW that he has grown apart from you - instead of 5 yrs down the road when you might have 2 or 3 children, married, house to split etc etc. Be looking for the "good" in a bad situation. It is not the end of the world and you have many many years to explore exactly what you want out of a man and life partner. I know it is hard -- been there and done that more times than once and it is never easy, no matter how old you get. You will love again - and you will be happy again. May be not till next month - or not till next year - but it WILL happen.
My youngest daughter who is 23, has a little 22 month old boy and recently her boyfriend of 5 yrs made the split. At first the devastation sets in ... crying etc ... but then you have to pick yourself up and go on. You AND your son deserve a healthy happy home and only you can make that happen. Fortunately, the baby's father and my daughter have worked things out well and have managed to remain friends for the good of their son who is loved greatly by both families. They trade off weekends, she has the baby one weekend so he can go out and have fun and then the next weekend he has the baby so she can go out and have fun. They actually live less than a mile from each other. They have agreed to not bring home a "friend" while they have the baby AND they still manage to do things as a family - go together this Thursday for the baby's first hair cut and go to doc appts together concerning the baby. Maybe you and your son's father can sit down and rationally think of what is best for your son together and make a plan that is fair for both sides. You must respect each other's privacy though and not question about dates etc in order to make it work.
Now as a single mom for 14 yrs w/3 little ones (I'm now 51 and a grandma of 6). I do know the heartache and struggle that you are faced with. That's why I must really stress that you do something nice for yourself from time to time. It could be something as simple as going to get your nails professionally done once a month, or you and a girlfriend going out for an ice cream and a movie. I never had financial NOR emotional support for any of the 3 kids ... that's why I know that you can do anything you set your mind too. Be patient with yourself :-)
Good Luck Sweetie -
