No one can tell you what to do, which I'm sure you already know. You could tell the new relationship person and let or play out (sometimes people will surprise you); you can opt to do a termination in secret (not sure how you want to add that aspect of keeping the secret and dealing with the new relationship), or you can choose to go it alone (which you know what that will already look like). I think these are all complicating issues. The real question is, outside relationships aside, are you financially and emotionally capable of having this baby? Do you want this baby (despite you perhaps being alone in it)? Can you choose either termination or adoption and follow through with either of those decisions? Maybe it would be best to talk to someone you can trust. I hope you find some answers. I'm sorry you are in this difficult situation.
