<human>: Give me the gist of the text in a nutshell

24 F

Hey Reddit! 
First post ever so bare with me! I have been with my boyfriend for just over 2 years. He is 22 and i am 24. I have finished school and have been well on my career for the past year, as he is still working his way through school. Unfortunately after the first year my boyfriend and I were together i ended up getting pregnant. We opted to not have the baby and move on as we were both not ready to have kids. A year and a half later i find out i am prego again. I am pretty excited, but i know after the last time with everything that happened my boyfriend will not be happy. He wanted no part of the baby AT ALL when this happened previously and was seriously frightened. As i was emotional and crazy i didn't really understand; for i had this human inside swooshing around! (We had a special bond even in the early weeks, something i think only a mother would understand) 
Not only that but... we have been on the rocks recently. On and off for the past 6 months (not sleeping with anyone else... just breaking it off and getting back together) 

I know this sounds horrible but after the last time with lack of support i feel like i should take the baby and make a life for us on our own. He didnt want have anything to do with it last time and i highly doubt anything has changed. So now to the question... should i save him the pain and just break it off officially and make a life for the baby and I? OR should i try and involve him and thoroughly expect him to be a fail father that he already admitted he would be.
<bot>: Just found out i was pregnant about 30 minutes ago FOR THE SECOND TIME ON BIRTH CONTROL and need to know if i should involve my SO.
