I am a parent, both by adoption and by birth, but am married. I have a good friend who is a single adoptive parent (we both adopted our children from the same country). Being a single adoptive parent is harder than being a single parent by birth. With some/many(?) exceptions, parenting children who have been adopted is a more challenging, interesting, complex, etc. experience. I speak as someone who is doing both...And, my observation is that being a single parent also has its unique challenges. So putting together being a single parent and being an adoptive parent is really going to be both fulfilling and challenging, with an emphasis on challenging, especially if you don't have family living close to you. If you are ready for the potential challenge, go for it.
