My rant

Me an my unborn child dad isn't together but he is 100% supportive when it comes to our child. He does have a gf but & I still love him, he is an awesome guy I really want to be with him but tonight I came to the conclusion that I'm just gone let that feeling of us being together go an let him live his life with his gf. If anyone was in a similar situation how did y get over you child father an accepted the fact that he has moved on an y'all won't be together? Even Tho u still love him
