What is the midpoint between $(-2,-3)$ and $\left(1, \frac{1}{2}\right) ?$
$\begin{array}{llll}\text { (A) }\left(-1,-2 \frac{1}{2}\right) & \text { (B }\left(-\frac{1}{2},-2 \frac{1}{2}\right) & \text { C }\left(-1,-1 \frac{1}{4}\right) & \text { \odot }\left(-\frac{1}{2},-1 \frac{1}{4}\right)\end{array}$
