Waiting for Her by S.A. Clayton

Max Winters has been in love with Addison Mitchell since he was sixteen. Being best friends with her brother made things a little more complicated and so he suppressed it, denying his feelings for over a decade.
Then she got pregnant.
Addison Mitchell never thought she would get pregnant by a man who loved football more than becoming a father. She always expected to end up with Max, her brother’s best friend, and secret fantasy. So when the father texts her that he wants nothing to do with her or the baby, she has to come to terms with being a single mother.
That is until Max turns up, suitcase in hand demanding that he stay with her until the baby arrives. But the longer they are together, the harder it gets for their feelings to be denied and so they have to decide if what they feel is worth the risk of losing everything.
