im just kind of confused and i would like an outsiders point of view please respond

Ok so I'm 17 and I finally have my first bf. Me and my boyfriend have been goin out for almost a month and this past Monday he called me saying, I really feel like a jerk, we didn't break up but I had no idea wat was goin on he hardly talked to me the whole 45 minutes we were on the phone, he kept telling me I was so nice and I didn't deserve to get my heart broken. I'm just so confused. We talked in person the next day and wat he told me is that he feels as though he lost the spark he felt when we first started goin out, but he said he wanted to still stay together to c if the spark will come back. I feel bad now cuz I feel as though I'm forcing him to go out wit me even though I asked him if he just wanted to break up and again he said he couldn't do that to me I didn't deserve it. Now I think back on it we kinda just jumped into the relationship, he not even a week after his ex of a little of a year broke up wit him they had a baby together which I don't mind he's wicked cute and a good baby to. But everytime I think of my bf I feel like were lost I just want to kno if its worth it to stay and see wat happens or should I break up wit him. We get along so well but now he's like 2 different people inside of skool and at his or my house. Help please!
