You should move on. This talk of loving each other is nonsense. You had two very short relationships. Your view of relationships and emotions seems to me to be extremely immature. Not just the talk of love after being together for all of five minutes, but the line "not attractively good looking but in a neutral way as I was in a relationship" is cute. Once you have matured a little you will come to realise that you cannot stop being attracted to other people, even when you're in a relationship, and being attracted to someone is not something that your other half, providing they are also mature, will be concerned about. Obviously going around announcing who you find attractive is probably not a great idea, but the important thing is that you can both trust each other not to act on and pursue people who you are attracted to. But pretending that you're not attracted to attractive people just because you're in a relationship is silly. It's not how that works.
So yeah, you need to grow up, and I don't mean that in a critical way. You're obviously reasonably young, and learning how to interact with girls and function in relationships is all part of what happens as you get older. It's something you learn about and hopefully get better at over time, and it never really stops. But yeah, if you can't stay with someone for longer than a few months after two attempts, there's no future in that. Move on to someone else, such as attractive people in clubs who give you their number when you ask for it.
