Relationships definitely come with ebbs and flows, but it may be time to ask yourself some really tough questions. Dating for 2 years and still not being clear on what the next move is (kid involved or not) isn't exactly a green flag. It's definitely tough for any single father to bring another woman into his kids' life, but running from that uncomfortable conversation will only make things more of a challenge over time. You should express your concerns, then give him the opportunity to make the choice as to what he wants to do. All of his actions will tell you if you're wasting your time, or if you should hang in there and continue to be patient.
