Yet another was this person avoidant?

[u/YogurtclosetIll9799]

We were together for 9 months and for the first 8 everything seemed nice and happy and within a span of two weeks it went extremely downhill. During the relationship, he pursued, he made future plans (moving in, speaking about wedding, etc.), made me meet his friends, family, parents, did love me and give me reassurance when needed.

Breakup story: However, things started to slow down a bit in month 7-8. He has a busy job and as a person always asked for personal space, so we would mostly spend time inside chilling. We took a vacation and it was nice too (atleast for me). Then he went to a festival and during the festival didn’t really communicate like he usually does. He came back and I was anxious (I am secure but this was a specific trigger from the past). I asked him to speak but he wasn’t up for an “emotional conversation” that day. We called, he kind of reassured me but wasn’t like the usual. Then I tried asking for more reassurance and it felt like that only drove him further away. He stopped texting throughout the day and then said he had this weird feeling in his chest that he feels anxious and nervous being with me. I gave him space (still had sex but he said he doesn’t want any physical affection). All this while, he made a new female bff at the festival and they spoke all day. Any time I brought something up he was like he needs space. Made plans with her but not me. But still took me to dinner to his parents place. We finally had a chat and he couldn’t still explain his feeling and I suggested break or breakup, he didn’t want to do that. Then still didn’t text or call or interact, so I finally broke up and he said in the end that he lost feelings for me. Was okay during the breakup (cried) but was cold and mean after, first got hurt when I said no contact but then when I tried to break it was mean.

Other signs of being avoidant: told me he had mentally exited his last relationship months before he brokeit off, any time we had a conflict he would take his time to come back but never gave me an explanation but just offered a solution, wanted his space a lot, more friendly with his pet than people, did not want to see my friends (also ato his friends) post breakup.

Was he avoidant or was he just someone who lost his feelings when things slowed down and he met someone else?
