Well, I have to someone who I appreciate tso much it's aand we are dateing. Well, I have someone who I appreciate so much and we are dating.

I am not really sure what you are trying to say here, but this is my guess.

Well, I have to someone whom I appreciate tso much it's awe're dateing. I have someone whom I appreciate so much we're dating.

What you meant by this sentence is a little unclear, but I've taken my best guess at it. Also, "well" is unnatural here. It's a tricky word to grasp though, so don't worry too much about it for now.

Also, we met at school and we wasere waiting a age more serious to have awhen we both had a more appropriate age to probably have a relationship. Also, we met at school and we were waiting when we both had a more appropriate age to probably have a relationship.

Also, wWe met at school and we wasre waiting afor an age more seriousmature to have a probablyotential relationship. We met at school and were waiting for an age more mature to have a potential relationship.

Omitting the "also" would sound more natural. At the start of a sentence, "also" makes whatever comes next seem like a fun fact, or a secondary piece of information that's of less importance. However, where the two of you met is obviously an important piece of information here. "we" is plural and should be used with "were". "age" begins with a vowel consonant" and should be used with "an".
