Is it better to marry a girl for love or because it makes sense?

There are 2 girls who I could potentially marry and I'm not even the marrying kind of guy until this past year, its been crazy, but anyways these girls are amazing. The first girl I am in love with but she was dating another guy and I havent talked to her since and I think she broke up with him and the 2nd one loves me and I like her alot but honestly am dating her bc she reminds me of the other girl who I couldnt have back then and we have a lot in common.

I met this first girl at an extracurricular class I was taking at a different place than my school so I only got to see her once a week. We hit it off and did lots of things including going to a dance one time and when we got to talking she told me she didnt have a bf and thats when I messed up terribly and didnt ask her out bc I thought I had more time. Well, she ended up dating another guy bc I was too late and at the end of the year, we said bye and it was awkward bc we both we wondering what if it hadnt played out this way but neither of us said anything and I didnt plan on going back to that extra class next year.

I met this other girl earlier that year and I liked her I think bc she seemed similar and even looks like that first girl and she had a lot in common with me so it seemed right and now I'm dating her and she says she wants to marry me. I thought I would get over that first girl in a few weeks but its been months and I havent, I only did for a while when I played football and I was literally at school almost all day for weeks and I was too tired to think about her. When life got back to a normal pace I thought about her a little but not too much and the 2nd girl also started going to that extracurricular place and wanted me to join her in a class and I thought that was fine. Ends up, since everything always goes wrong for me unless I think of all the possibilities, that she had to drop out and guess what, that first girl was in the class and of course she looks at me all the time and is all nice bc I think she has broken up with that guy but I didnt even say a word to her bc the only way I got through that year after she said no was to convince myself she was a bitch for doing that but really, she isn't and I just had to trick myself into thinking that to make myself believe she wasnt worth killing myself over. I've dated a lot of girls but none of them meant anything because it was high school and we were just having fun but these 2 girls are just so different and I like it. The first girl was my first real love and after it didnt work out I've never felt the same towards any other girl and just as a person, I feel less carefree like I use to be.

Anyways, I don't know for sure if I could get back together with her again and explain why I didnt ask her out earlier but I'm pretty sure I can. The thing is I really do care about the 2nd girl who says she wants to marry me and I've helped her come from being really sad to really happy but I'm starting to think I just wanted to help save her from her abusive parents and terrible "friends" because I knew what they were really like. It went to far though and she does have a lot of qualities now that I look for in a girl but I just don't get that feeling like I can go days without thinking of her, I couldnt go a minute without thinking of the first girl. I'm wondering if I sortve lost a little piece of myself and will never trust anyone like I trusted that girl, so the reason I dont feel that way for that girl is just I never will so maybe I should settle down with her bc she really loves me and is smart and pretty, etc. but on the otherhand I dont want to get a divorce like lots of people do bc they didnt marry the person they loved and settled for ok. What should I do?
