I would say that I am not an expert when it comes to relationships by any means. Heck, I have never dated, seriously. However, the one thing that stands out for me with this show is that Andy seems genuine and honest. It could be the Fleiss editing, lol! However, Andy appears to consistently want to genuinely get to know all of the women, but the one thing that we all must remember is that as much as they try to make us believe that his heart is still in the air. It is not. As a human being, you know what you want. Andy has known or believe he knows what he wants by the show now. However, I believe the problem is that he has always wanted Tessa, but he does not know if Tessa wants him. So, he constantly tries to make her feel better and wants her to realize his feelings without saying, hey Tessa, you are the one I want for me. So, he is protecting himself too. Therefore, I believe Tessa is the one because he has not gone after her like everyone else. He could have let her go long time ago when she was not reciprocating his feelings. But, the thing that stands out for me, is that he did not. He could have. From the beginning, he could have said I don't want to keep going with this, but what I constantly think is why keep her. Andy does not appear to be a cold jerk, but I could be wrong. I just constantly wonder why he decided to keep her if she is not the one.
My thoughts on who is the final is not based on liking Tessa more than Bevin. Disliking Bevin. I liked Bevin early on and she was probably the favorite for me, but I just constantly saw something with Tessa and Andy, and it would hurt me to see that after this girl who does not open up easily, who does not reveal her feelings easily or openly, who was so scared and apprehensive, who definitely makes it to the finale- She is on the screencaps-is only taken all this way to be hurt in the end.
Andy is not saying be my girlfriend. He is asking someone to marry him. If he knew he was going to do this and believed he found his wife, for me, why take Tessa along-who was scared of being hurt etc., only to really hurt her in the beginning. This means that he was deciding between one and two if this is the case. I don't believe he was. I believe that he knew exactly from episode 5 that he was going to choose a woman TO marry. I do not believe, since Tessa is the final one he would take her to the finale if she is not the one. This is just me.
I am getting very long-winded but wanted to explain why I believe it is Tessa.
