Letter to a confused friend

Hi Alex, how are you? That's fantastic! If I were you, I wouldn't know what to do either. 18
Firstly, it's necessary to know how much money is it and once I know, I will be able to help you in a better way. 42
Last week, I watched an ad on TV about a new computer game. It is very realistic, with very good graphics and for 65
all ages. When I watched, I though: I would like to have enough money to buy it! 82
On the other hand, Sales will start on Monday. If you prefer to go shopping instead of buying the computer game, 103
then will be the best moment to do it because it will be possible to buy more pieces of clothes. 123
From my point of view, if I didn't need anything, I would save it. Maybe, in some days, there is 143
something that really loves me and I can buy it. 153
Finally, I'm waiting for your reply about how much money you have. Maybe, you are worried about choosing 171
between two options and you have enough money to buy both of them. 184
Kisses, 185

Hi Alex,

How are you?

That's fantastic! If I were you, I wouldn't know what to do either. 18
Firstly, it's necessary to know how much money it costs and once I know, I will be able to help you in a better way to decide what to do. 42
Last week, I watched an ad on TV about a new computer game. It is very realistic with very good graphics and for 65
all ages. When I watched the video, I thought: I would like to have enough money to buy it! 82
On the other hand, Sales will start on Monday. If you prefer to go shopping then instead of buying the computer game right away, 103
then Monday will be the best time to buy because it will be possible to buy more pieces of clothes. 123
From my point of view, if I didn't need anything, I would save it. Maybe, in the future there will be 143
something that I really love and I can buy it instead. 153
Finally, I'm waiting for your reply about how much money you have. Maybe, you are worried about choosing 171
between two options and if you have enough money to buy both of them. 184
Kisses, 185

Notes:

 I don't follow some of the writing without knowing more. I would reword it a bit as highlighted below  the original. I also am unsure why the numbers of words needs to be on there line by line. I would maybe do word count aftrer each section or at the end as it just makes it a little awkward I think.
