Pregnant and In a relationship and lonely

First I wanna give you some back ground information. I grew up with my boyfriend he was my brothers best friend and also mine. We have been on and off for about 2-4 years he’s about two and a half years younger than me. We have been together now for a year on the 22nd and he’s told me a few times that he don’t love me anymore that he’s only with me to be able to see his baby he just told me again that he don’t even wanna be here with me. He apologized for that and said he only said it cause he was mad. Truth comes out when your mad I know that I feel so lonely and so depressed and I can’t even go to him for comfort he’s the only person I feel like I have. I’m close with all my family and I know they are there to support me through this but I love him with all my heart and I’m trying to hang on for this baby. I grew up with the best dad I could ask for and I want my daughter to have a dad like I had. I don’t even know if I should give her his last name. He’s been there for me so far but it just brakes my heart I’m 26 weeks so we don’t have long I’m terrified of doing this without him.
