What does this dream mean?

It made me feel weird. I dont have a girlfriend but i dreamed i did and it just started like hey we have a baby girl, that i never saw. Idk but the rest is just alot of lolly gaggin. I swore off of relationships since iv bin cheated on alot or it never worked out, i literally felt my heart hurt when her ex told me that she was cheating on the both of us. Him and i are friends now lol. And the sad part is im only 15 and swore to never love a girl again, cant have the kids i wanted... but anyways that dream felt real and i love dreams like that but do any of you know what it means ? The dream seemed like it lasted for hours.
