Hey, first off - welcome to TeenHelp
I really think you should talk to him about how you
really feel. If you keep that inside, he's going to expect you to get an abortion and when you don't, he's going to be confused. It's really important to be honest about your feelings in this subject. If you guys are trying to work on your relationship, how would you hide the pregnancy from him? Would you leave him? Like I said, I believe honesty is very important. Talk about your feelings and make the best decision for both of you. It's ultimately YOUR decision. If you're against abortion, what about adoption? Could you do that? If he really loves you, he will support you and stay by your side despite what you chose to do. Also, before you make any decisions; you need to find out if your in fact pregnant or not!
I'm gonna leave this with good luck and if you ever need to talk, feel free to message me anytime. I wish you the best<3
