Cancer man... Interested or not?

I realize astrology does not dictate the happenings of a relationship nor are descriptions always accurate to each individual. So pretty please don't be too harsh or critical of me!

I've been friends with a Cancer man for around 3 years now. In the beginning of our friendship it was very clear he had feelings for me and wanted something more. At the time however, I was engaged and did not want to jeopardize my relationship, so I kept my cancer friend at an arms length and he being the gentleman he is, respected it. I couldn't deny that I had developed feelings for him though. (Never told him) Also huge plus, his mom used to really like me! Not sure now, however she's been nice to me! They are at odds with each other at the moment unfortunately. Time goes by, we talk and hangout less and less. I get married, he has a girlfriend, they have a baby. Etc. Time goes on further, I end up divorcing my now ex husband. (We have since gotten back together, but currently in the process of breaking things off) cancer friend goes through a few bad relationships. He always pops back up in my life periodically though to talk and check in. It's taken time, but I have undoubtedly matured and realized what it is I need and want in somebody, and I find myself thinking of him after all of this time. A few days ago he asked me to hang out with him and his daughter, it was great.. Until his mom and him got into a bit of an argument in front of me. He's been a little distant since then. We have plans to hangout again when I get back from a trip out of state. I'm at a loss. I know it's going to require lots of patience on my part to win him over, but I have always really liked and respected this guy. Obviously he's far more cautious about who he's dating and letting into his life these days due to his daughter. However, my intentions are pure, and I'm okay with him having a child, and willing to be there for both of them. I'm an Aries and obviously being subtle isn't my strong suit. However I'm doing my best at being coy, and also showing interest in him. It's difficult! Now that we MAY have a shot at something more than friendship I can't tell if he's still interested. I don't want to waste his or my time. I'm the one who's doing the chasing and I feel very unsure and left second guessing my actions. We were talking yesterday and then he quit responding. I haven't said anything to him today, vice versa. However he's liked several things on my social media. Should I take the initiative, or perhaps give him space? I know I can't rush things, but it's difficult not knowing where him and I stand. I feel like he's interested at times, and then at others like he isn't. I realize I can't go in guns blazing or be clingy.. As it will scare him away.. I would love if things worked out in my favor, but accept the possibility of him not being interested romantically. Any helpful advice or tips? Thanks for reading!
