For a friend, I'm posting it here because I would need mature advice

Please a friend need your advice

Mid last year, a female friend ask about my relationship status which I told her that I just broke up, she said she'll connect me with a friend which she did, the lady and I started chatting and a week or two after, we met, to be sincere she was a little bit below average in beauty, when we got back home she told me she likes me and asked if I like her too, I didn't like her to be honest but I don't know how I will tell her that she isn't as beautiful as I want. I'm not really about breast and all but someone just average but she's below par. The reasons why I said yes was because

1. I don't want to spoil her self esteem
2. I just broke up and needed someone to clear it off my mind because I was working from home and I do remember how we were anytime I'm free because I and the previous lady used to talk every day, we never missed a day until something went wrong so I needed someone to take the place so I was channeling the energy then to the new lady
Time went by so fast and now I would move out of the country soon and she's asking what we are going to do, I'm confused, I don't even know if I should leave the relationship.

Reasons why I don't want to break up yet

1. Where I'm moving to isn't a place with a lot of good choice for spouse for both gender, it's also lonely there, according to singles over there

2. This girl is very homely, we do see once a month and she would help with all the house chores, from laundry to cooking, I will even be the one telling her not to stress herself but she wouldn't hear me

3. I don't want to hurt her, she asked me sometimes this year if I wouldn't betray her or ask any girl out and I told her only God knows tomorrow and she flared up and even told our friend, she thought it was because I casually ask her if she would allow me to have *, she's still a virgin and I won't have anything to do with that because I'm not sure of where the relationship is heading and I wouldn't want to add that to the equation

The reason why I just want to move on is because

1) She's below average in beauty sincerely

2) She has NCE and going back for BSc but her conversation is like someone without waec maybe because she grew up in rural side of Ibadan, I don't used to mind education but she can't hold a decent conversation in English

I don't just know what to do, I don't want to waste her time if I'm not doing I would like to tell now but I don't even know how to say it, she once told me about someone that was trying to get her number and I was hinting her that she can watch out for any one she likes but she didn't get the memo

Moved this thread to Romance section so we can do justice to it
