Too early to be this unhappy at 6mths
New to the group. Let me get right into it. I have been dating a man for the past 6mths. I am 31, 4 kids. Him 40, 2 kids. We live an hour from eachother, but I work in the same town as him. He came on really strong in the beginning. Talked about marriage, wanting to be with me, calling all the time, spending tons of time. As of late we have both been super busy with work, travel etc. We did spend Thanksgiving together with the kids in CO, then planned to spend X-mas in STL with all of us. Needless to say we had been snappy with eachother lately. Primarily due to the stresses of everything. I have been extra so due to lack of time & him backing off from how he was in the beginning. He broke up with me, then we got back together right before the holiday. Ended up going to STL with the kids & it was horrible. I couldn't get over the events that led up to us not spending as much time together was to get us on track before we put all of us together. He said I was explosive, snapping at the kids. I kept mentioning stuff to them like keeping seat belts on in the car. Safety stuff, mind you I never yelled or anything. So not great evening & the next morning he informs me that him & his two kids had gotten another room in a different hotel. I was obviously upset, we had driven down there together. I was 5 hours from home with my 5 kids. He stated we would spend time together, they would just be sleeping somewhere else. We didn't spend time together because I was just distraught over this. He did drive us back home at the end of the trip. Fast forward & we got back together, but it's different. No talks of marriage, progressing things, etc. Rarely calls when his kids are there, usually only does when he runs out of the house for a few minutes. I'm just not sure what I need to do. I feel almost cheated & maybe he is just passing time with me. I love this man, but not sure if I am being a fool. He still says I am the love of his life, but I wonder if he is being legit, if he's spending time with someone else since he's not spending as much time with him (he says it isn't), but when he has his kids he'll be on FB messenger all day & making posts & talking to people (I can see them).
What to do?
