Person I'm dating with seems losing interest
[32M] For context, when we first matched with each other, we texted and talked over the phone quite often. We then went on 4 dates in total and agreed to be exclusive. Due to our schedules, we haven't seen each other for a month (we've been talking with each other for 2 months, all of our dates happened in the first month). We are planning to see each other this weekend however, I'm feeling something do not sit right while we're talking/texting with each other. During the month that we didn't see each other, when we texted/called, her responses were not as enthusiastic/excited as she used to. When I tried to make plan for us, she mostly gave me responses like "I dont know" or "I'm not sure." It took a while for us to finally to land a date this weekend however, I tried to text/discuss with her about the plan for 3 days, but I haven't got the confirmation from her if she's interested in my plan or not. I'm not sure if I'm thinking into it too much, or should I just (at this point) wait for her response/confirmation to my plan rather than keep texting her? I just want to get some perspective as if this is a sign of withdrawal or does she not feel interested in this anymore? I'm a little bit confused as she's really hot/cold on her communication. When we texted each other during a month bream, there were time we said we both missed each other while there were time that she's just ignored some of my "feelings" messages. Thank you all!
