I dont know what to do💔🥺

So me an an ex been on and off for about 4 years now…like one minute we stop talking an then we start talking again..but in between we been in and out of relationships with other people like we will talk to each other then stop an then date other people or just have them as a close friend an then leave them an be drawn back to each other…he hurt me a couple times in the past… so we clearly are talking again this will be the 4th time so he has been telling me that he want to be more then friends now an that he is not letting nothing get in the way of us being together an that we can go as slow as i want to as long as he has me next to him an he even deleted all the other females out of his life…this is the first time with me he has done that and the first time we dated he would not let me see his phone but now when i ask for it he hands it to me like he is giving me a freaking gift or something…he has been non stop wanting to text an call me an see me every day..when we stopped talking he hAs been with 3 women after me an i havent been with guy i just kept them as a friend until i felt like i was ready to date again …so he asked me if i could see a future with him an i said yes… but a couple of days ago i told him i dont want to be with anyone right now i told him that i dont want to be with anyone right now because i feel like these past 4 years of me being single i felt like i needed that an im scared to change it an it will be what i didn’t expect…the day i told him that…he cried while he was at work an he got sent home early because of what was going on they told him he should see a counselor …he keeps saying he guess its his karma for the way he treated me years ago…..we just had a whole argument about that conversation he keeps bringing it up like i know it’s bothering him deep down inside he says he knows that im happy alone an he will accept it an respect my wishes an he is not leaving my side because he knows he dont want anyone else but me…we both cried together…i cried because i know deeep down inside i want to be with him but scared later on in life it will be different an i seriously dont want to lose him again…he says we can be friends for now an see what the future holds🥺💔 at this very moment he said he needs his space because his heart is still shattered an he needs to get his mind off of some things so he stopped texting me for about 2 hours now💔
