Adoption

**(Sorry if posted in wrong place. I just know there is many mothers and opinionated people in this group is why I posted it here) **
I'm not looking to be judged. I just need advice. . I haven't fully decided but I'm considering so I'm reaching out.. I'm even in tears as I write this because I love this baby so much. I just feel I can't be selfish.. I know myself and boyfriend can not properly care and provide for my baby as well as another family could. Some pros are, my baby wouldn't experience financial problems, better chance of college, a non broken home. Etc.. I don't want my baby to go without anything ever. I love him/her so much that I would do this out of love. I'm really scared my baby would not understand and have hard feelings towards me and that's not what I want. I really want an open adoption but I'm scared that will make it worse because the baby will not understand why they can't go home with me and it'll crush me to leave everytime. 
I know in an adoption home the baby will never want or need anything. Never question if it's father figure loves them.. because another reason I've deeply thought about it is because I feel he is not ready.. many reasons why but I'm not here to bash or talk about him. I'm 17 and he's 18. I would never consider abortion because I feel my baby is a baby, and it deserves a good life. I just need thoughts and all opinions are welcome. I'm not a selfish mother.. I'm literally balling my eyes out writing this but I have no where else to go or talk to about it because my family is beyond excited about having a new baby so I just don't want to crush them just yet.. I can't talk to my boyfriend about it either because every time I even say the word he shuts it down real quick and won't let me explain myself.. 😔
