<p>He stopped from being Parker's "mentor" after Homecoming, he cannot even be considered as a mentor, as he did not teach him anything at all about being a hero (excluding the Ferry scene) nor he was a father figure to him. Parker only admired him which makes sens as he was 14-15 years old when he met his hero.</p><p>
</p><p>Back to the main point, Stark stopped from being the mentor and I highly dount that he and Parker would keep in touch frequently over the two years between Homecoming and Infinity War. </p><p>
</p><p>So, yeah, there is no reason to keep him around again. </p>

<p>happy is a strong evidence suggesting tony is still around somewhere, unless the trailer used the same trick that it's actually hulk flirting with aunt may</p>

<p>They clearly have reseted the Snap. </p>

<p>stark is alive</p>

<p>just wait for the movie</p><p>
