Should He Go Ahead & Marry This Lady Despite Her 'Bad' Sides?

A story by Iamtheweather

I met my fiancee some few yrs ago. I've agreed to marry her but there are factors I still want to give a final consideration before signing the dotted lines.

These are:
1. She is not literate but willing to go to school. I never dreamt of marrying an illiterate when I, myself is a graduate. Her waec result is nothing to write home about. In fact she wasted her time in secondary school as far as I'm concerned and when I asked her why she was such an olodo, she quickly blamed those she lived with. She said because she was more or less a maid then, she hadn't much time for her studies and that's why she failed woefully. When I met her, her use of english was zero and I had to exert much effort to bring her to the level where she could converse freely with me at least in english. She retook her ssce and credited all subjects except math.

2. She's 2yrs and 3months older than me. Some argue that a woman will age first when older and that's the reason men go for younger women or at worst, their age mates.

3: She sometimes feel inferior to me cos' of my literacy and polished way of going about my stuff.

4. She has a fat tummy. This I perceived to be an upshot of her eating habit before I met her. Can you believe that it was when I started staying close to her that I discovered that she doesn't drink water after eating. Maybe she does that very much later. She was an expert in devouring meat with her friends and never exercised. I also had to teach her to drink water first thing in the morning before taking breakfast. I discovered that her mouth was always dry as a result of this disgusting lifestyle. If she wants to have a word with me in low tone, I do perceive some offensive odours from the mouth sometimes. All this are changing slowly now cos' a damage of so many years can't just be corrected overnight. I'm putting much effort into rearing her cos' she's a wife material.
There are one or two other drawbacks I won't like to go into now as the aforementioned factors are the ones that baffle me the most. I sometimes get so annoyed and start abusing her. But she also has her good sides that even attracted me to her which are:
1. She is well-mannered.
2. She can cook very well.
3. She is very hospitable.
4. She's very respectful.
5: She's pretty and fair.
6. She's a wife material.
7. She's reserved.
The crux here is that we are presently, not on the same page as far as being learned and refined is concerned and I want to marry someone who'll be very refined as well. Though we stay as friends but I feel she doesn't measure up.
So my people, if you were in my shoes, can you go ahead and marry her despite these bad sides??
Pls and pls, helpful comments will suffice.
