Unplanned Pregnancy Decisions

Hi, I found out 2 days ago I am 5weeks pregnant! My boyfriend doesn't want it, I'm in two minds! I have been with my boyfriend for 2years, we are only young 23/24! We both live with our parents we see each other practically every day and have been saving for a flat for a while! We have often spoke about marriage and kids in the future! And I know my boyfriend is right when he says we are not ready, financially especially, we don't live together yet and we wanted to go on loads of holidays this year! I just havnt stopped crying since I found out, he has said he wouldn't force me to do anything I don't want; and I really don't think I want a termination, even though it would be best for the baby at this time! And I don't want to force my boyfriend to do something he doesn't want! He has said we should wait and try again in the future as this isn't the right time, why do I know he is right but still want to keep it? I know I am being hormonal and just keep crying, even my boyfriend cried when I told him I wasn't sure! He is really not ready and I would feel like a horrible person keeping it when I know it is not ideal and he doesn't want me to! I just think I will feel horrible and empty if I terminate it! I don't know what to do, or what to think, I just want to cry! I'm on the pill by the way so still don't know why this even happened to me!
